+- [35621](https://github.com/apache/superset/pull/35621): The default hash algorithm has changed from MD5 to SHA-256 for improved security and FedRAMP compliance. This affects cache keys for thumbnails, dashboard digests, chart digests, and filter option names. Existing cached data will be invalidated upon upgrade. To opt out of this change and maintain backward compatibility, set `HASH_ALGORITHM = "md5"` in your `superset_config.py`.
 - [33055](https://github.com/apache/superset/pull/33055): Upgrades Flask-AppBuilder to 5.0.0. The AUTH_OID authentication type has been deprecated and is no longer available as an option in Flask-AppBuilder. OpenID (OID) is considered a deprecated authentication protocol - if you are using AUTH_OID, you will need to migrate to an alternative authentication method such as OAuth, LDAP, or database authentication before upgrading.
 - [35062](https://github.com/apache/superset/pull/35062): Changed the function signature of `setupExtensions` to `setupCodeOverrides` with options as arguments.
 - [34871](https://github.com/apache/superset/pull/34871): Fixed Jest test hanging issue from Ant Design v5 upgrade. MessageChannel is now mocked in test environment to prevent rc-overflow from causing Jest to hang. Test environment only - no production impact.

 - [32432](https://github.com/apache/superset/pull/31260) Moves the List Roles FAB view to the frontend and requires `FAB_ADD_SECURITY_API` to be enabled in the configuration and `superset init` to be executed.
 - [34319](https://github.com/apache/superset/pull/34319) Drill to Detail and Drill By is now supported in Embedded mode, and also with the `DASHBOARD_RBAC` FF. If you don't want to expose these features in Embedded / `DASHBOARD_RBAC`, make sure the roles used for Embedded / `DASHBOARD_RBAC`don't have the required permissions to perform D2D actions.
 
+### Breaking Changes
+
+#### CUSTOM_FONT_URLS removed
+
+The `CUSTOM_FONT_URLS` configuration option has been removed. Use the new per-theme `fontUrls` token in `THEME_DEFAULT` or database-managed themes instead.
+
+**Before (5.x):**
+```python
+CUSTOM_FONT_URLS = [
+    "https://fonts.example.com/myfont.css",
+]
+```
+
+**After (6.0):**
+```python
+THEME_DEFAULT = {
+    "token": {
+        "fontUrls": [
+            "https://fonts.example.com/myfont.css",
+        ],
+        # ... other tokens
+    }
+}
+```

 ## 5.0.0
 
 - [31976](https://github.com/apache/superset/pull/31976) Removed the `DISABLE_LEGACY_DATASOURCE_EDITOR` feature flag. The previous value of the feature flag was `True` and now the feature is permanently removed.

+
+## Usage in Extensions
+
+This component is available in the `@apache-superset/core/ui` package, which is automatically available to Superset extensions.
+
+```tsx
+import { Alert } from '@apache-superset/core/ui';
+
+function MyExtension() {
+  return (
+    <Alert
+      closable
+      type="info"

+# Extension Components
+
+These UI components are available to Superset extension developers through the `@apache-superset/core/ui` package. They provide a consistent look and feel with the rest of Superset and are designed to be used in extension panels, views, and other UI elements.
+
+## Available Components
+
+- [Alert](./alert)
+
+## Usage
+
+All components are exported from the `@apache-superset/core/ui` package:
+
+```tsx
+import { Alert } from '@apache-superset/core/ui';
+
+export function MyExtensionPanel() {
+  return (
+    <Alert type="info">
+      Welcome to my extension!
+    </Alert>
+  );
+}
+```
+
+## Adding New Components
+
+Components in `@apache-superset/core/ui` are automatically documented here. To add a new extension component:
+
+1. Add the component to `superset-frontend/packages/superset-core/src/ui/components/`
+2. Export it from `superset-frontend/packages/superset-core/src/ui/components/index.ts`
+3. Create a Storybook story with an `Interactive` export:
+
+```tsx
+export default {
+  title: 'Extension Components/MyComponent',
+  component: MyComponent,
+  parameters: {
+    docs: {
+      description: {
+        component: 'Description of the component...',
+      },
+    },
+  },
+};
+
+export const InteractiveMyComponent = (args) => <MyComponent {...args} />;
+
+InteractiveMyComponent.args = {
+  variant: 'primary',
+  disabled: false,
+};
+
+InteractiveMyComponent.argTypes = {
+  variant: {
+    control: { type: 'select' },
+    options: ['primary', 'secondary'],
+  },
+  disabled: {
+    control: { type: 'boolean' },
+  },
+};
+```
+
+4. Run `yarn start` in `docs/` - the page generates automatically!

+
+## Contributing Extension-Compatible Components
+
+Components in `@apache-superset/core` are automatically documented in the Developer Portal. Simply add a component to the package and it will appear in the extension documentation.
+
+### Requirements
+
+1. **Location**: The component must be in `superset-frontend/packages/superset-core/src/ui/components/`
+2. **Exported**: The component must be exported from the package's `index.ts`
+3. **Story**: The component must have a Storybook story
+
+### Creating a Story for Your Component
+
+Create a story file with an `Interactive` export that defines args and argTypes:
+
+```typescript
+// MyComponent.stories.tsx
+import { MyComponent } from '.';
+
+export default {
+  title: 'Extension Components/MyComponent',
+  component: MyComponent,
+  parameters: {
+    docs: {
+      description: {
+        component: 'A brief description of what this component does.',
+      },
+    },
+  },
+};
+
+// Define an interactive story with args
+export const InteractiveMyComponent = (args) => <MyComponent {...args} />;
+
+InteractiveMyComponent.args = {
+  variant: 'primary',
+  disabled: false,
+};
+
+InteractiveMyComponent.argTypes = {
+  variant: {
+    control: { type: 'select' },
+    options: ['primary', 'secondary', 'danger'],
+  },
+  disabled: {
+    control: { type: 'boolean' },
+  },
+};
+```
+
+### How Documentation is Generated
+
+When the docs site is built (`yarn start` or `yarn build` in the `docs/` directory):
+
+1. The `generate-extension-components` script scans all stories in `superset-core`
+2. For each story, it generates an MDX page with:
+   - Component description
+   - **Live interactive example** with controls extracted from `argTypes`
+   - **Editable code playground** for experimentation
+   - Props table from story `args`
+   - Usage code snippet
+   - Links to source files
+3. Pages appear automatically in **Developer Portal → Extensions → Components**
+
+### Best Practices
+
+- **Use descriptive titles**: The title path determines the component's location in docs (e.g., `Extension Components/Alert`)
+- **Define argTypes**: These become interactive controls in the documentation
+- **Provide default args**: These populate the initial state of the live example
+- **Write clear descriptions**: Help extension developers understand when to use each component

 A Data Access Object (DAO) is a pattern that provides an abstract interface to the SQLAlchemy Object Relational Mapper (ORM). The DAOs are critical as they form the building block of the application which are wrapped by the associated commands and RESTful API endpoints.
 
-Currently there are numerous inconsistencies and violation of the DRY principal within the codebase as it relates to DAOs and ORMs—unnecessary commits, non-ACID transactions, etc.—which makes the code unnecessarily complex and convoluted. Addressing the underlying issues with the DAOs _should_ help simplify the downstream operations and improve the developer experience.

Addressing the underlying issues with the DAOs _should_ help simplify the downstream operations and improve the developer experience.
 
 To ensure consistency the following rules should be adhered to:
 
-1. All database operations (including testing) should be defined within a DAO, i.e., there should not be any explicit `db.session.add`, `db.session.merge`, etc. calls outside of a DAO.
+## Core Rules
 
-2. A DAO should use `create`, `update`, `delete`, `upsert` terms—typical database operations which ensure consistency with commands—rather than action based terms like `save`, `saveas`, `override`, etc.
+1. **All database operations (including testing) should be defined within a DAO**, i.e., there should not be any explicit `db.session.add`, `db.session.merge`, etc. calls outside of a DAO.
 
-3. Sessions should be managed via a [context manager](https://docs.sqlalchemy.org/en/20/orm/session_transaction.html#begin-once) which auto-commits on success and rolls back on failure, i.e., there should be no explicit `db.session.commit` or `db.session.rollback` calls within the DAO.
+2. **A DAO should use `create`, `update`, `delete`, `upsert` terms**—typical database operations which ensure consistency with commands—rather than action based terms like `save`, `saveas`, `override`, etc.
 
-4. There should be a single atomic transaction representing the entirety of the operation, i.e., when creating a dataset with associated columns and metrics either all the changes succeed when the transaction is committed, or all the changes are undone when the transaction is rolled back. SQLAlchemy supports [nested transactions](https://docs.sqlalchemy.org/en/20/orm/session_transaction.html#nested-transaction) via the `begin_nested` method which can be nested—inline with how DAOs are invoked.

+6. **Exception-based validation**: Ask for forgiveness rather than permission. Try to perform the operation and rely on database constraints to verify that the model is acceptable, rather than pre-validating conditions.
+
+7. **Bulk operations**: Provide bulk `create`, `update`, and `delete` methods where applicable for performance optimization.
+
+8. **Sparse updates**: Updates should only modify explicitly defined attributes.

 ## Button Design Guidelines
 
@@ -98,6 +117,32 @@ Primary buttons have a fourth style: dropdown.
 | Tertiary | For less prominent actions; can be used in isolation or paired with a primary button |
 | Destructive | For actions that could have destructive effects on the user's data |
 
+### Format
+
+#### Anatomy
+
+Button text is centered using the Label style. Icons appear left of text when combined. If no text label exists, an icon must indicate the button's function.
+
+#### Button size
+
+- Default dimensions: 160px width × 32px height
+- Text: 11px, Inter Medium, all caps
+- Corners: 4px border radius
+- Minimum padding: 8px around text
+- Width can decrease if space is limited, but maintain minimum padding
+
+#### Button groups
+
+- Group related buttons to establish visual hierarchy
+- Avoid overwhelming users with too many actions
+- Limit calls to action; use tertiary/ghost buttons for layouts with 3+ actions
+- Maintain consistent styles within groups when possible
+- Space buttons 8px apart vertically or horizontally
+
+#### Content guidelines
+
+Button labels should be clear and predictable. Use the "\{verb\} + \{noun\}" format, except for common actions like "Done," "Close," "Cancel," "Add," or "Delete." This formula provides necessary context and aids translation, though compact UIs or localization needs may warrant exceptions.

+- For app-wide errors, use the top of the screen
+
+### Content guidelines
+
+Effective error messages communicate:
+
+1. What went wrong
+2. What users should do next
+
+Error messages should be:
+
+- Clear and accurate, leaving no room for misinterpretation
+- Short and concise
+- Understandable to non-technical users

-## Component Development Best Practices
+**Reference naming:** Use `PascalCase` for React components and `camelCase` for component instances
 
-### Use TypeScript
-
-All new components should be written in TypeScript. This helps catch errors early and provides better development experience with IDE support.
-
-```tsx
-interface ComponentProps {
-  title: string;
-  isVisible?: boolean;
-  onClose?: () => void;
-}
-
-export const MyComponent: React.FC<ComponentProps> = ({
-  title,
-  isVisible = true,
-  onClose
-}) => {
-  // Component implementation
-};
+**BAD:**
+```jsx
+import mainNav from './MainNav';
 ```
 
-### Prefer Functional Components
+**GOOD:**
+```jsx
+import MainNav from './MainNav';
+```
 
-Use functional components with hooks instead of class components:
+**BAD:**
+```jsx
+const NavItem = <MainNav />;
+```
+
+**GOOD:**
+```jsx
+const navItem = <MainNav />;
+```
+
+**Component naming:** Use the file name as the component name
+
+**BAD:**
+```jsx
+import MainNav from './MainNav/index';
+```
+
+**GOOD:**
+```jsx
+import MainNav from './MainNav';
+```
+
+**Props naming:** Do not use DOM related props for different purposes
+
+**BAD:**
+```jsx
+<MainNav style="big" />
+```
+
+**GOOD:**
+```jsx
+<MainNav variant="big" />
+```
+
+**Importing dependencies:** Only import what you need
+
+**BAD:**
+```jsx
+import * as React from "react";
+```
+
+**GOOD:**
+```jsx
+import React, { useState } from "react";
+```
+
+**Default VS named exports:** As recommended by [TypeScript](https://www.typescriptlang.org/docs/handbook/modules.html), "If a module's primary purpose is to house one specific export, then you should consider exporting it as a default export. This makes both importing and actually using the import a little easier". If you're exporting multiple objects, use named exports instead.
+
+_As a default export_
+```jsx
+import MainNav from './MainNav';
+```
+
+_As a named export_
+```jsx
+import { MainNav, SecondaryNav } from './Navbars';
+```
+
+**ARIA roles:** Always make sure you are writing accessible components by using the official [ARIA roles](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques)
+
+## Use TypeScript
+
+All components should be written in TypeScript and their extensions should be `.ts` or `.tsx`
+
+### type vs interface
+
+Validate all props with the correct types. This replaces the need for a run-time validation as provided by the prop-types library.
 
 ```tsx
-// ✅ Good - Functional component with hooks
-export const MyComponent: React.FC<Props> = ({ data }) => {
-  const [loading, setLoading] = useState(false);
+type HeadingProps = {
+  param: string;
+}
 
-  useEffect(() => {
-    // Effect logic
-  }, []);
-
-  return <div>{/* Component JSX */}</div>;
-};
-
-// ❌ Avoid - Class component
-class MyComponent extends React.Component {
-  // Class implementation
+export default function Heading({ children }: HeadingProps) {
+  return <h2>{children}</h2>
 }
 ```
 
-### Follow Ant Design Patterns
+Use `type` for your component props and state. Use `interface` when you want to enable _declaration merging_.
 
-Extend Ant Design components rather than building from scratch:
+### Define default values for non-required props
+
+In order to improve the readability of your code and reduce assumptions, always add default values for non required props, when applicable, for example:
 
 ```tsx
-import { Button } from 'antd';
-import styled from '@emotion/styled';
-
-const StyledButton = styled(Button)`
-  // Custom styling using emotion
-`;
+const applyDiscount = (price: number, discount = 0.05) => price * (1 - discount);
 ```
 
-### Reusability and Props Design
+## Functional components and Hooks
 
-Design components with reusability in mind:
+We prefer functional components and the usage of hooks over class components.
+
+### useState
+
+Always explicitly declare the type unless the type can easily be assumed by the declaration.
 
 ```tsx
-interface ButtonProps {
-  variant?: 'primary' | 'secondary' | 'tertiary';
-  size?: 'small' | 'medium' | 'large';
-  loading?: boolean;
-  disabled?: boolean;
-  children: React.ReactNode;
-  onClick?: () => void;
-}
-
-export const CustomButton: React.FC<ButtonProps> = ({
-  variant = 'primary',
-  size = 'medium',
-  ...props
-}) => {
-  // Implementation
-};
+const [customer, setCustomer] = useState<ICustomer | null>(null);
 ```
 
-## Testing Components
+### useReducer
 
-Every component should include comprehensive tests:
+Always prefer `useReducer` over `useState` when your state has complex logics.
 
-```tsx
-// MyComponent.test.tsx
-import { render, screen, fireEvent } from '@testing-library/react';
-import { MyComponent } from './MyComponent';
+### useMemo and useCallback
 
-test('renders component with title', () => {
-  render(<MyComponent title="Test Title" />);
-  expect(screen.getByText('Test Title')).toBeInTheDocument();
-});
+Always memoize when your components take functions or complex objects as props to avoid unnecessary rerenders.
 
-test('calls onClose when close button is clicked', () => {
-  const mockOnClose = jest.fn();
-  render(<MyComponent title="Test" onClose={mockOnClose} />);
+### Custom hooks
 
-  fireEvent.click(screen.getByRole('button', { name: /close/i }));
-  expect(mockOnClose).toHaveBeenCalledTimes(1);
-});
-```
+All custom hooks should be located in the directory `/src/hooks`. Before creating a new custom hook, make sure that is not available in the existing custom hooks.
 
-## Storybook Stories
+## Storybook
 
-Create stories for visual testing and documentation:
+Each component should come with its dedicated storybook file.
 
-```tsx
-// MyComponent.stories.tsx
-import type { Meta, StoryObj } from '@storybook/react';
-import { MyComponent } from './MyComponent';
+**One component per story:** Each storybook file should only contain one component unless substantially different variants are required
 
-const meta: Meta<typeof MyComponent> = {
-  title: 'Components/MyComponent',
-  component: MyComponent,
-  parameters: {
-    layout: 'centered',
-  },
-  tags: ['autodocs'],
-};
+**Component variants:** If the component behavior is substantially different when certain props are used, it is best to separate the story into different types. See the `superset-frontend/src/components/Select/Select.stories.tsx` as an example.
 
-export default meta;
-type Story = StoryObj<typeof meta>;
+**Isolated state:** The storybook should show how the component works in an isolated state and with as few dependencies as possible
 
-export const Default: Story = {
-  args: {
-    title: 'Default Component',
-    isVisible: true,
-  },
-};
-
-export const Hidden: Story = {
-  args: {
-    title: 'Hidden Component',
-    isVisible: false,
-  },
-};
-```
-
-## Performance Considerations
-
-### Use React.memo for Expensive Components
-
-```tsx
-import React, { memo } from 'react';
-
-export const ExpensiveComponent = memo<Props>(({ data }) => {
-  // Expensive rendering logic
-  return <div>{/* Component content */}</div>;
-});
-```
-
-### Optimize Re-renders
-
-Use `useCallback` and `useMemo` appropriately:
-
-```tsx
-export const OptimizedComponent: React.FC<Props> = ({ items, onSelect }) => {
-  const expensiveValue = useMemo(() => {
-    return items.reduce((acc, item) => acc + item.value, 0);
-  }, [items]);
-
-  const handleSelect = useCallback((id: string) => {
-    onSelect(id);
-  }, [onSelect]);
-
-  return <div>{/* Component content */}</div>;
-};
-```
-
-## Accessibility
-
-Ensure components are accessible:
-
-```tsx
-export const AccessibleButton: React.FC<Props> = ({ children, onClick }) => {
-  return (
-    <button
-      type="button"
-      aria-label="Descriptive label"
-      onClick={onClick}
-    >
-      {children}
-    </button>
-  );
-};
-```
-
-## Error Boundaries
-
-For components that might fail, consider error boundaries:
-
-```tsx
-export const SafeComponent: React.FC<Props> = ({ children }) => {
-  return (
-    <ErrorBoundary fallback={<div>Something went wrong</div>}>
-      {children}
-    </ErrorBoundary>
-  );
-};
-```
+**Use args:** It should be possible to test the component with every variant of the available props. We recommend using [args](https://storybook.js.org/docs/react/writing-stories/args)

+
+## Emotion Tips and Strategies
+
+The first thing to consider when adding styles to an element is how much you think a style might be reusable in other areas of Superset. Always err on the side of reusability here. Nobody wants to chase styling inconsistencies, or try to debug little endless overrides scattered around the codebase. The more we can consolidate, the less will have to be figured out by those who follow. Reduce, reuse, recycle.
 
 ## When to use `css` or `styled`
 
-### Use `css` for:
+In short, either works for just about any use case! And you'll see them used somewhat interchangeably in the existing codebase. But we need a way to weigh it when we encounter the choice, so here's one way to think about it:
 
-1. **Small, single-use styles**
-```tsx
-import { css } from '@emotion/react';
+A good use of `styled` syntax if you want to re-use a styled component. In other words, if you wanted to export flavors of a component for use, like so:
 
-const MyComponent = () => (
-  <div
-    css={css`
-      margin: 8px;
-      padding: 16px;
-    `}
-  >
-    Content
-  </div>
-);
-```
-
-2. **Composing styles**
-```tsx
-const baseStyles = css`
-  padding: 16px;
-  border-radius: 4px;
+```jsx
+const StatusThing = styled.div`
+  padding: 10px;
+  border-radius: 10px;
 `;
 
-const primaryStyles = css`
-  ${baseStyles}
-  background-color: blue;
-  color: white;
+export const InfoThing = styled(StatusThing)`
+  background: blue;
+  &::before {
+    content: "ℹ️";
+  }
 `;
 
-const secondaryStyles = css`
-  ${baseStyles}
-  background-color: gray;
-  color: black;
+export const WarningThing = styled(StatusThing)`
+  background: orange;
+  &::before {
+    content: "⚠️";
+  }
 `;
-```
 
-3. **Conditional styling**
-```tsx
-const MyComponent = ({ isActive }: { isActive: boolean }) => (
-  <div
-    css={[
-      baseStyles,
-      isActive && activeStyles,
-    ]}
-  >
-    Content
-  </div>
-);
-```
-
-### Use `styled` for:
-
-1. **Reusable components**
-```tsx
-import styled from '@emotion/styled';
-
-const StyledButton = styled.button`
-  padding: 12px 24px;
-  border: none;
-  border-radius: 4px;
-  background-color: ${({ theme }) => theme.colors.primary};
-  color: white;
-
-  &:hover {
-    background-color: ${({ theme }) => theme.colors.primaryDark};
+export const TerribleThing = styled(StatusThing)`
+  background: red;
+  &::before {
+    content: "🔥";
   }
 `;
 ```
 
-2. **Components with complex nested selectors**
-```tsx
-const StyledCard = styled.div`
-  padding: 16px;
-  border: 1px solid ${({ theme }) => theme.colors.border};
+You can also use `styled` when you're building a bigger component, and just want to have some custom bits for internal use in your JSX. For example:
 
-  .card-header {
-    font-weight: bold;
-    margin-bottom: 8px;
-  }
-
-  .card-content {
-    color: ${({ theme }) => theme.colors.text};
-
-    p {
-      margin-bottom: 12px;
-    }
-  }
+```jsx
+const SeparatorOnlyUsedInThisComponent = styled.hr`
+  height: 12px;
+  border: 0;
+  box-shadow: inset 0 12px 12px -12px rgba(0, 0, 0, 0.5);
 `;
+
+function SuperComplicatedComponent(props) {
+  return (
+    <>
+      Daily standup for {user.name}!
+      <SeparatorOnlyUsedInThisComponent />
+      <h2>Yesterday:</h2>
+      // spit out a list of accomplishments
+      <SeparatorOnlyUsedInThisComponent />
+      <h2>Today:</h2>
+      // spit out a list of plans
+      <SeparatorOnlyUsedInThisComponent />
+      <h2>Tomorrow:</h2>
+      // spit out a list of goals
+    </>
+  );
+}
 ```
 
-3. **Extending Ant Design components**
-```tsx
-import { Button } from 'antd';
-import styled from '@emotion/styled';
+The `css` prop, in reality, shares all the same styling capabilities as `styled` but it does have some particular use cases that jump out as sensible. For example, if you just want to style one element in your component, you could add the styles inline like so:
 
-const CustomButton = styled(Button)`
-  border-radius: 8px;
-  font-weight: 600;
-
-  &.ant-btn-primary {
-    background: linear-gradient(45deg, #1890ff, #722ed1);
-  }
-`;
+```jsx
+function SomeFanciness(props) {
+  return (
+    <>
+      Here's an awesome report card for {user.name}!
+      <div
+        css={css`
+          box-shadow: 5px 5px 10px #ccc;
+          border-radius: 10px;
+        `}
+      >
+        <h2>Yesterday:</h2>
+        // ...some stuff
+        <h2>Today:</h2>
+        // ...some stuff
+        <h2>Tomorrow:</h2>
+        // ...some stuff
+      </div>
+    </>
+  );
+}
 ```
 
-## Using Theme Variables
+You can also define the styles as a variable, external to your JSX. This is handy if the styles get long and you just want it out of the way. This is also handy if you want to apply the same styles to disparate element types, kind of like you might use a CSS class on varied elements. Here's a trumped up example:
 
-Always use theme variables for consistent styling:
-
-```tsx
-import { useTheme } from '@emotion/react';
-
-const MyComponent = () => {
-  const theme = useTheme();
+```jsx
+function FakeGlobalNav(props) {
+  const menuItemStyles = css`
+    display: block;
+    border-bottom: 1px solid cadetblue;
+    font-family: "Comic Sans", cursive;
+  `;
 
   return (
-    <div
-      css={css`
-        background-color: ${theme.colors.grayscale.light5};
-        color: ${theme.colors.grayscale.dark2};
-        padding: ${theme.gridUnit * 4}px;
-        border-radius: ${theme.borderRadius}px;
-      `}
-    >
-      Content
+    <Nav>
+      <a css={menuItemStyles} href="#">One link</a>
+      <Link css={menuItemStyles} to={url}>Another link</Link>
+      <div css={menuItemStyles} onClick={() => alert('clicked')}>Another link</div>
+    </Nav>
+  );
+}
+```
+
+## CSS tips and tricks
+
+### `css` lets you write actual CSS
+
+By default the `css` prop uses the object syntax with JS style definitions, like so:
+
+```jsx
+<div css={{
+  borderRadius: 10,
+  marginTop: 10,
+  backgroundColor: '#00FF00'
+}}>Howdy</div>
+```
+
+But you can use the `css` interpolator as well to get away from icky JS styling syntax. Doesn't this look cleaner?
+
+```jsx
+<div css={css`
+  border-radius: 10px;
+  margin-top: 10px;
+  background-color: #00FF00;
+`}>Howdy</div>
+```
+
+You might say "whatever… I can read and write JS syntax just fine." Well, that's great. But… let's say you're migrating in some of our legacy LESS styles… now it's copy/paste! Or if you want to migrate to or from `styled` syntax… also copy/paste!
+
+### You can combine `css` definitions with array syntax
+
+You can use multiple groupings of styles with the `css` interpolator, and combine/override them in array syntax, like so:
+
+```jsx
+function AnotherSillyExample(props) {
+  const shadowedCard = css`
+    box-shadow: 2px 2px 4px #999;
+    padding: 4px;
+  `;
+  const infoCard = css`
+    background-color: #33f;
+    border-radius: 4px;
+  `;
+  const overrideInfoCard = css`
+    background-color: #f33;
+  `;
+  return (
+    <div className="App">
+      Combining two classes:
+      <div css={[shadowedCard, infoCard]}>Hello</div>
+      Combining again, but now with overrides:
+      <div css={[shadowedCard, infoCard, overrideInfoCard]}>Hello</div>
     </div>
   );
-};
-```
-
-## Common Patterns
-
-### Responsive Design
-```tsx
-const ResponsiveContainer = styled.div`
-  display: flex;
-  flex-direction: column;
-
-  ${({ theme }) => theme.breakpoints.up('md')} {
-    flex-direction: row;
-  }
-`;
-```
-
-### Animation
-```tsx
-const FadeInComponent = styled.div`
-  opacity: 0;
-  transition: opacity 0.3s ease-in-out;
-
-  &.visible {
-    opacity: 1;
-  }
-`;
-```
-
-### Conditional Props
-```tsx
-interface StyledDivProps {
-  isHighlighted?: boolean;
-  size?: 'small' | 'medium' | 'large';
 }
+```
 
-const StyledDiv = styled.div<StyledDivProps>`
-  padding: 16px;
-  background-color: ${({ isHighlighted, theme }) =>
-    isHighlighted ? theme.colors.primary : theme.colors.grayscale.light5};
+### Style variations with props
 
-  ${({ size }) => {
-    switch (size) {
-      case 'small':
-        return css`font-size: 12px;`;
-      case 'large':
-        return css`font-size: 18px;`;
-      default:
-        return css`font-size: 14px;`;
-    }
-  }}
+You can give any component a custom prop, and reference that prop in your component styles, effectively using the prop to turn on a "flavor" of that component.
+
+For example, let's make a styled component that acts as a card. Of course, this could be done with any AntD component, or any component at all. But we'll do this with a humble `div` to illustrate the point:
+
+```jsx
+const SuperCard = styled.div`
+  ${({ theme, cutout }) => `
+    padding: ${theme.gridUnit * 2}px;
+    border-radius: ${theme.borderRadius}px;
+    box-shadow: 10px 5px 10px #ccc ${cutout && 'inset'};
+    border: 1px solid ${cutout ? 'transparent' : theme.colors.secondary.light3};
+  `}
 `;
 ```
 
-## Best Practices
+Then just use the component as `<SuperCard>Some content</SuperCard>` or with the (potentially dynamic) prop: `<SuperCard cutout>Some content</SuperCard>`
 
-### 1. Use Semantic CSS Properties
-```tsx
-// ✅ Good - semantic property names
-const Header = styled.h1`
-  font-size: ${({ theme }) => theme.typography.sizes.xl};
-  margin-bottom: ${({ theme }) => theme.gridUnit * 4}px;
-`;
+## Styled component tips
 
-// ❌ Avoid - magic numbers
-const Header = styled.h1`
-  font-size: 24px;
-  margin-bottom: 16px;
-`;
-```
+### No need to use `theme` the hard way
 
-### 2. Group Related Styles
-```tsx
-// ✅ Good - grouped styles
-const Card = styled.div`
-  /* Layout */
-  display: flex;
-  flex-direction: column;
-  padding: ${({ theme }) => theme.gridUnit * 4}px;
+It's very tempting (and commonly done) to use the `theme` prop inline in the template literal like so:
 
-  /* Appearance */
-  background-color: ${({ theme }) => theme.colors.grayscale.light5};
-  border: 1px solid ${({ theme }) => theme.colors.grayscale.light2};
+```jsx
+const SomeStyledThing = styled.div`
+  padding: ${({ theme }) => theme.gridUnit * 2}px;
   border-radius: ${({ theme }) => theme.borderRadius}px;
-
-  /* Typography */
-  font-family: ${({ theme }) => theme.typography.families.sansSerif};
-  color: ${({ theme }) => theme.colors.grayscale.dark2};
+  border: 1px solid ${({ theme }) => theme.colors.secondary.light3};
 `;
 ```
 
-### 3. Extract Complex Styles
-```tsx
-// ✅ Good - extract complex styles to variables
-const complexGradient = css`
-  background: linear-gradient(
-    135deg,
-    ${({ theme }) => theme.colors.primary} 0%,
-    ${({ theme }) => theme.colors.secondary} 100%
-  );
-`;
+Instead, you can make things a little easier to read/type by writing it like so:
 
-const GradientButton = styled.button`
-  ${complexGradient}
-  padding: 12px 24px;
-  border: none;
-  color: white;
+```jsx
+const SomeStyledThing = styled.div`
+  ${({ theme }) => `
+    padding: ${theme.gridUnit * 2}px;
+    border-radius: ${theme.borderRadius}px;
+    border: 1px solid ${theme.colors.secondary.light3};
+  `}
 `;
 ```
 
-### 4. Avoid Deep Nesting
-```tsx
-// ✅ Good - shallow nesting
-const Navigation = styled.nav`
-  .nav-item {
-    padding: 8px 16px;
-  }
+## Extend an AntD component with custom styling
 
-  .nav-link {
-    color: ${({ theme }) => theme.colors.text};
-    text-decoration: none;
-  }
+As mentioned, you want to keep your styling as close to the root of your component system as possible, to minimize repetitive styling/overrides, and err on the side of reusability. In some cases, that means you'll want to globally tweak one of our core components to match our design system. In Superset, that's Ant Design (AntD).
+
+AntD uses a cool trick called compound components. For example, the `Menu` component also lets you use `Menu.Item`, `Menu.SubMenu`, `Menu.ItemGroup`, and `Menu.Divider`.
+
+### The `Object.assign` trick
+
+Let's say you want to override an AntD component called `Foo`, and have `Foo.Bar` display some custom CSS for the `Bar` compound component. You can do it effectively like so:
+
+```jsx
+import {
+  Foo as AntdFoo,
+} from 'antd';
+
+export const StyledBar = styled(AntdFoo.Bar)`
+  border-radius: ${({ theme }) => theme.borderRadius}px;
 `;
 
-// ❌ Avoid - deep nesting
-const Navigation = styled.nav`
-  ul {
-    li {
-      a {
-        span {
-          color: blue; /* Too nested */
-        }
-      }
-    }
-  }
-`;
-```
-
-## Performance Tips
-
-### 1. Avoid Inline Functions in CSS
-```tsx
-// ✅ Good - external function
-const getBackgroundColor = (isActive: boolean, theme: any) =>
-  isActive ? theme.colors.primary : theme.colors.secondary;
-
-const Button = styled.button<{ isActive: boolean }>`
-  background-color: ${({ isActive, theme }) => getBackgroundColor(isActive, theme)};
-`;
-
-// ❌ Avoid - inline function (creates new function on each render)
-const Button = styled.button<{ isActive: boolean }>`
-  background-color: ${({ isActive, theme }) =>
-    isActive ? theme.colors.primary : theme.colors.secondary};
-`;
-```
-
-### 2. Use CSS Objects for Dynamic Styles
-```tsx
-// For highly dynamic styles, consider CSS objects
-const dynamicStyles = (props: Props) => ({
-  backgroundColor: props.color,
-  fontSize: `${props.size}px`,
-  // ... other dynamic properties
+export const Foo = Object.assign(AntdFoo, {
+  Bar: StyledBar,
 });
-
-const DynamicComponent = (props: Props) => (
-  <div css={dynamicStyles(props)}>
-    Content
-  </div>
-);
 ```
+
+You can then import this customized `Foo` and use `Foo.Bar` as expected. You should probably save your creation in `src/components` for maximum reusability, and add a Storybook entry so future engineers can view your creation, and designers can better understand how it fits the Superset Design System.

-# Testing Guidelines and Best Practices
-
-We feel that tests are an important part of a feature and not an additional or optional effort. That's why we colocate test files with functionality and sometimes write tests upfront to help validate requirements and shape the API of our components. Every new component or file added should have an associated test file with the `.test` extension.
-
-We use Jest, React Testing Library (RTL), and Cypress to write our unit, integration, and end-to-end tests. For each type, we have a set of best practices/tips described below:
-
-## Jest
-
-### Write simple, standalone tests
-
-The importance of simplicity is often overlooked in test cases. Clear, dumb code should always be preferred over complex ones. The test cases should be pretty much standalone and should not involve any external logic if not absolutely necessary. That's because you want the corpus of the tests to be easy to read and understandable at first sight.
-
-### Avoid nesting when you're testing
-
-Avoid the use of `describe` blocks in favor of inlined tests. If your tests start to grow and you feel the need to group tests, prefer to break them into multiple test files. Check this awesome [article](https://kentcdodds.com/blog/avoid-nesting-when-youre-testing) written by [Kent C. Dodds](https://kentcdodds.com/) about this topic.
-
-### No warnings!
-
-Your tests shouldn't trigger warnings. This is really common when testing async functionality. It's really difficult to read test results when we have a bunch of warnings.
-
-## React Testing Library (RTL)
-
-### Keep accessibility in mind when writing your tests
-
-One of the most important points of RTL is accessibility and this is also a very important point for us. We should try our best to follow the RTL [Priority](https://testing-library.com/docs/queries/about/#priority) when querying for elements in our tests. `getByTestId` is not viewable by the user and should only be used when the element isn't accessible in any other way.
-
-### Don't use `act` unnecessarily
-
-`render` and `fireEvent` are already wrapped in `act`, so wrapping them in `act` again is a common mistake. Some solutions to the warnings related to async testing can be found in the RTL docs.
-
-## Example Test Structure
-
-```tsx
-// MyComponent.test.tsx
-import { render, screen, fireEvent, waitFor } from '@testing-library/react';
-import userEvent from '@testing-library/user-event';
-import { MyComponent } from './MyComponent';
-
-// ✅ Good - Simple, standalone test
-test('renders loading state initially', () => {
-  render(<MyComponent />);
-  expect(screen.getByText('Loading...')).toBeInTheDocument();
-});
-
-// ✅ Good - Tests user interaction
-test('calls onSubmit when form is submitted', async () => {
-  const user = userEvent.setup();
-  const mockOnSubmit = jest.fn();
-
-  render(<MyComponent onSubmit={mockOnSubmit} />);
-
-  await user.type(screen.getByLabelText('Username'), 'testuser');
-  await user.click(screen.getByRole('button', { name: 'Submit' }));
-
-  expect(mockOnSubmit).toHaveBeenCalledWith({ username: 'testuser' });
-});
-
-// ✅ Good - Tests async behavior
-test('displays error message when API call fails', async () => {
-  const mockFetch = jest.fn().mockRejectedValue(new Error('API Error'));
-  global.fetch = mockFetch;
-
-  render(<MyComponent />);
-
-  await waitFor(() => {
-    expect(screen.getByText('Error: API Error')).toBeInTheDocument();
-  });
-});
-```
-
-## Testing Best Practices
-
-### Use appropriate queries in priority order
-
-1. **Accessible to everyone**: `getByRole`, `getByLabelText`, `getByPlaceholderText`, `getByText`
-2. **Semantic queries**: `getByAltText`, `getByTitle`
-3. **Test IDs**: `getByTestId` (last resort)
-
-```tsx
-// ✅ Good - using accessible queries
-test('user can submit form', () => {
-  render(<LoginForm />);
-
-  const usernameInput = screen.getByLabelText('Username');
-  const passwordInput = screen.getByLabelText('Password');
-  const submitButton = screen.getByRole('button', { name: 'Log in' });
-
-  // Test implementation
-});
-
-// ❌ Avoid - using test IDs when better options exist
-test('user can submit form', () => {
-  render(<LoginForm />);
-
-  const usernameInput = screen.getByTestId('username-input');
-  const passwordInput = screen.getByTestId('password-input');
-  const submitButton = screen.getByTestId('submit-button');
-
-  // Test implementation
-});
-```
-
-### Test behavior, not implementation details
-
-```tsx
-// ✅ Good - tests what the user experiences
-test('shows success message after successful form submission', async () => {
-  render(<ContactForm />);
-
-  await userEvent.type(screen.getByLabelText('Email'), 'test@example.com');
-  await userEvent.click(screen.getByRole('button', { name: 'Submit' }));
-
-  await waitFor(() => {
-    expect(screen.getByText('Message sent successfully!')).toBeInTheDocument();
-  });
-});
-
-// ❌ Avoid - testing implementation details
-test('calls setState when form is submitted', () => {
-  const component = shallow(<ContactForm />);
-  const instance = component.instance();
-  const spy = jest.spyOn(instance, 'setState');
-
-  instance.handleSubmit();
-  expect(spy).toHaveBeenCalled();
-});
-```
-
-### Mock external dependencies appropriately
-
-```tsx
-// Mock API calls
-jest.mock('../api/userService', () => ({
-  getUser: jest.fn(),
-  createUser: jest.fn(),
-}));
-
-// Mock components that aren't relevant to the test
-jest.mock('../Chart/Chart', () => {
-  return function MockChart() {
-    return <div data-testid="mock-chart">Chart Component</div>;
-  };
-});
-```
-
-## Async Testing Patterns
-
-### Testing async operations
-
-```tsx
-test('loads and displays user data', async () => {
-  const mockUser = { id: 1, name: 'John Doe' };
-  const mockGetUser = jest.fn().mockResolvedValue(mockUser);
-
-  render(<UserProfile getUserData={mockGetUser} />);
-
-  // Wait for the async operation to complete
-  await waitFor(() => {
-    expect(screen.getByText('John Doe')).toBeInTheDocument();
-  });
-
-  expect(mockGetUser).toHaveBeenCalledTimes(1);
-});
-```
-
-### Testing loading states
-
-```tsx
-test('shows loading spinner while fetching data', async () => {
-  const mockGetUser = jest.fn().mockImplementation(
-    () => new Promise(resolve => setTimeout(resolve, 100))
-  );
-
-  render(<UserProfile getUserData={mockGetUser} />);
-
-  expect(screen.getByText('Loading...')).toBeInTheDocument();
-
-  await waitFor(() => {
-    expect(screen.queryByText('Loading...')).not.toBeInTheDocument();
-  });
-});
-```
-
-## Component-Specific Testing
-
-### Testing form components
-
-```tsx
-test('validates required fields', async () => {
-  render(<RegistrationForm />);
-
-  const submitButton = screen.getByRole('button', { name: 'Register' });
-  await userEvent.click(submitButton);
-
-  expect(screen.getByText('Username is required')).toBeInTheDocument();
-  expect(screen.getByText('Email is required')).toBeInTheDocument();
-});
-```
-
-### Testing modals and overlays
-
-```tsx
-test('opens and closes modal', async () => {
-  render(<ModalContainer />);
-
-  const openButton = screen.getByRole('button', { name: 'Open Modal' });
-  await userEvent.click(openButton);
-
-  expect(screen.getByRole('dialog')).toBeInTheDocument();
-
-  const closeButton = screen.getByRole('button', { name: 'Close' });
-  await userEvent.click(closeButton);
-
-  expect(screen.queryByRole('dialog')).not.toBeInTheDocument();
-});
-```
-
-### Testing with context providers
-
-```tsx
-const renderWithTheme = (component: React.ReactElement) => {
-  return render(
-    <ThemeProvider theme={mockTheme}>
-      {component}
-    </ThemeProvider>
-  );
-};
-
-test('applies theme colors correctly', () => {
-  renderWithTheme(<ThemedButton />);
-
-  const button = screen.getByRole('button');
-  expect(button).toHaveStyle({
-    backgroundColor: mockTheme.colors.primary,
-  });
-});
-```
-
-## Performance Testing
-
-### Testing with large datasets
-
-```tsx
-test('handles large lists efficiently', () => {
-  const largeDataset = Array.from({ length: 10000 }, (_, i) => ({
-    id: i,
-    name: `Item ${i}`,
-  }));
-
-  const { container } = render(<VirtualizedList items={largeDataset} />);
-
-  // Should only render visible items
-  const renderedItems = container.querySelectorAll('[data-testid="list-item"]');
-  expect(renderedItems.length).toBeLessThan(100);
-});
-```
-
-## Testing Accessibility
-
-```tsx
-test('is accessible to screen readers', () => {
-  render(<AccessibleForm />);
-
-  const form = screen.getByRole('form');
-  const inputs = screen.getAllByRole('textbox');
-
-  inputs.forEach(input => {
-    expect(input).toHaveAttribute('aria-label');
-  });
-
-  expect(form).toHaveAttribute('aria-describedby');
-});
-```

+
+### No warnings!
+
+Your tests shouldn't trigger warnings. This is really common when testing async functionality. It's really difficult to read test results when we have a bunch of warnings.
+
+### Example
+
+You can find an example of a test [here](https://github.com/apache/superset/blob/e6c5bf4/superset-frontend/src/common/hooks/useChangeEffect/useChangeEffect.test.ts).
+
+## React Testing Library (RTL)
+
+### Keep accessibility in mind when writing your tests
+
+One of the most important points of RTL is accessibility and this is also a very important point for us. We should try our best to follow the RTL [Priority](https://testing-library.com/docs/queries/about/#priority) when querying for elements in our tests. `getByTestId` is not viewable by the user and should only be used when the element isn't accessible in any other way.
+
+### Don't use `act` unnecessarily
+
+`render` and `fireEvent` are already wrapped in `act`, so wrapping them in `act` again is a common mistake. Some solutions to the warnings related to `act` might be found [here](https://kentcdodds.com/blog/fix-the-not-wrapped-in-act-warning).
+
+### Be specific when using *ByRole
+
+By using the `name` option we can point to the items by their accessible name. For example:
+
+```jsx
+screen.getByRole('button', { name: /hello world/i })
+```
+
+Using the `name` property also avoids breaking the tests in the future if other components with the same role are added.
+
+### userEvent vs fireEvent
+
+Prefer the [user-event](https://github.com/testing-library/user-event) library, which provides a more advanced simulation of browser interactions than the built-in [fireEvent](https://testing-library.com/docs/dom-testing-library/api-events/#fireevent) method.
+
+### Usage of waitFor
+
+- [Prefer to use `find`](https://kentcdodds.com/blog/common-mistakes-with-react-testing-library#using-waitfor-to-wait-for-elements-that-can-be-queried-with-find) over `waitFor` when you're querying for elements. Even though both achieve the same objective, the `find` version is simpler and you'll get better error messages.
+- Prefer to use only [one assertion at a time](https://kentcdodds.com/blog/common-mistakes-with-react-testing-library#having-multiple-assertions-in-a-single-waitfor-callback). If you put multiple assertions inside a `waitFor` we could end up waiting for the whole block timeout before seeing a test failure even if the failure occurred at the first assertion. By putting a single assertion in there, we can improve on test execution time.
+- Do not perform [side-effects](https://kentcdodds.com/blog/common-mistakes-with-react-testing-library#performing-side-effects-in-waitfor) inside `waitFor`. The callback can be called a non-deterministic number of times and frequency (it's called both on an interval as well as when there are DOM mutations). So this means that your side-effect could run multiple times.
+
+### Example
+
+You can find an example of a test [here](https://github.com/apache/superset/blob/master/superset-frontend/src/dashboard/components/PublishedStatus/PublishedStatus.test.tsx).
+
+## Cypress
+
+### Prefer to use Cypress for e2e testing and RTL for integration testing
+
+Here it's important to make the distinction between e2e and integration testing. This [article](https://www.onpathtesting.com/blog/end-to-end-vs-integration-testing) gives an excellent definition:
+
+> End-to-end testing verifies that your software works correctly from the beginning to the end of a particular user flow. It replicates expected user behavior and various usage scenarios to ensure that your software works as whole. End-to-end testing uses a production equivalent environment and data to simulate real-world situations and may also involve the integrations your software has with external applications.
+
+> A typical software project consists of multiple software units, usually coded by different developers. Integration testing combines those software units logically and tests them as a group.
+> Essentially, integration testing verifies whether or not the individual modules or services that make up your application work well together. The purpose of this level of testing is to expose defects in the interaction between these software modules when they are integrated.
+
+Do not use Cypress when RTL can do it better and faster. Many of the Cypress tests that we have right now, fall into the integration testing category and can be ported to RTL which is much faster and gives more immediate feedback. Cypress should be used mainly for end-to-end testing, replicating the user experience, with positive and negative flows.
+
+### Isolated and standalone tests
+
+Tests should never rely on other tests to pass. This might be hard when a single user is used for testing as data will be stored in the database. At every new test, we should reset the database.
+
+### Cleaning state
+
+Cleaning the state of the application, such as resetting the DB, or in general, any state that might affect consequent tests should always be done in the `beforeEach` hook and never in the `afterEach` one as the `beforeEach` is guaranteed to run, while the test might never reach the point to run the `afterEach` hook. One example would be if you refresh Cypress in the middle of the test. At this point, you will have built up a partial state in the database, and your clean-up function will never get called. You can read more about it [here](https://docs.cypress.io/guides/references/best-practices#Using-after-or-afterEach-hooks).
+
+### Unnecessary use of `cy.wait`
+
+- Unnecessary when using `cy.request()` as it will resolve when a response is received from the server
+- Unnecessary when using `cy.visit()` as it resolves only when the page fires the load event
+- Unnecessary when using `cy.get()`. When the selector should wait for a request to happen, aliases would come in handy:
+
+```js
+cy.intercept('GET', '/users', [{ name: 'Maggy' }, { name: 'Joan' }]).as('getUsers')
+cy.get('#fetch').click()
+cy.wait('@getUsers') // <--- wait explicitly for this route to finish
+cy.get('table tr').should('have.length', 2)
+```
+
+### Accessibility and Resilience
+
+The same accessibility principles in the RTL section apply here. Use accessible selectors when querying for elements. Those principles also help to isolate selectors from eventual CSS and JS changes and improve the resilience of your tests.

+### Understanding Context Availability
+
+Some Jinja variables like `from_dttm`, `to_dttm`, and `filter` are **only available when a chart or dashboard provides them**. They are populated from:
+
+- Time range filters applied in Explore/Chart views
+- Dashboard native filters
+- Filter components
+
+**These variables are NOT available in standalone SQL Lab queries** because there's no filter context. If you try to use `{{ from_dttm }}` directly in SQL Lab, you'll get an "undefined parameter" error.
+
+#### Testing Time-Filtered Queries in SQL Lab
+
+To test queries that use time variables in SQL Lab, you have several options:
+
+**Option 1: Use Jinja defaults (recommended)**
+
+```sql
+SELECT *
+FROM tbl
+WHERE dttm_col > '{{ from_dttm | default("2024-01-01", true) }}'
+  AND dttm_col < '{{ to_dttm | default("2024-12-31", true) }}'
+```
+
+**Option 2: Use SQL Lab Parameters**
+
+Set parameters in the SQL Lab UI (Parameters menu):
+```json
+{
+  "from_dttm": "2024-01-01",
+  "to_dttm": "2024-12-31"
+}
+```
+
+**Option 3: Use `{% set %}` for testing**
+
+```sql
+{% set from_dttm = "2024-01-01" %}
+{% set to_dttm = "2024-12-31" %}
+SELECT *
+FROM tbl
+WHERE dttm_col > '{{ from_dttm }}' AND dttm_col < '{{ to_dttm }}'
+```
+
+:::tip
+When you save a SQL Lab query as a virtual dataset and use it in a chart with time filters,
+the actual filter values will override any defaults or test values you set.

+# Extension Components
+
+These UI components are available to Superset extension developers through the \`@apache-superset/core/ui\` package. They provide a consistent look and feel with the rest of Superset and are designed to be used in extension panels, views, and other UI elements.
+
+## Available Components
+
+${componentList}
+
+## Usage
+
+All components are exported from the \`@apache-superset/core/ui\` package:
+
+\`\`\`tsx
+import { Alert } from '@apache-superset/core/ui';
+
+export function MyExtensionPanel() {
+  return (
+    <Alert type="info">
+      Welcome to my extension!
+    </Alert>
+  );
+}
+\`\`\`
+
+## Adding New Components
+
+Components in \`@apache-superset/core/ui\` are automatically documented here. To add a new extension component:
+
+1. Add the component to \`superset-frontend/packages/superset-core/src/ui/components/\`
+2. Export it from \`superset-frontend/packages/superset-core/src/ui/components/index.ts\`
+3. Create a Storybook story with an \`Interactive\` export:
+
+\`\`\`tsx
+export default {
+  title: 'Extension Components/MyComponent',
+  component: MyComponent,
+  parameters: {
+    docs: {
+      description: {
+        component: 'Description of the component...',
+      },
+    },
+  },
+};
+
+export const InteractiveMyComponent = (args) => <MyComponent {...args} />;
+
+InteractiveMyComponent.args = {
+  variant: 'primary',
+  disabled: false,
+};
+
+InteractiveMyComponent.argTypes = {
+  variant: {
+    control: { type: 'select' },
+    options: ['primary', 'secondary'],
+  },
+  disabled: {
+    control: { type: 'boolean' },
+  },
+};
+\`\`\`
+
+4. Run \`yarn start\` in \`docs/\` - the page generates automatically!
+

 Note that the Jinja parameters are called within _double_ brackets in the query and with
 _single_ brackets in the logic blocks.
 
+### Understanding Context Availability
+
+Some Jinja variables like `from_dttm`, `to_dttm`, and `filter` are **only available when a chart or dashboard provides them**. They are populated from:
+
+- Time range filters applied in Explore/Chart views
+- Dashboard native filters
+- Filter components
+
+**These variables are NOT available in standalone SQL Lab queries** because there's no filter context. If you try to use `{{ from_dttm }}` directly in SQL Lab, you'll get an "undefined parameter" error.
+
+#### Testing Time-Filtered Queries in SQL Lab
+
+To test queries that use time variables in SQL Lab, you have several options:
+
+**Option 1: Use Jinja defaults (recommended)**
+
+```sql
+SELECT *
+FROM tbl
+WHERE dttm_col > '{{ from_dttm | default("2024-01-01", true) }}'
+  AND dttm_col < '{{ to_dttm | default("2024-12-31", true) }}'
+```
+
+**Option 2: Use SQL Lab Parameters**
+
+Set parameters in the SQL Lab UI (Parameters menu):
+```json
+{
+  "from_dttm": "2024-01-01",
+  "to_dttm": "2024-12-31"
+}
+```
+
+**Option 3: Use `{% set %}` for testing**
+
+```sql
+{% set from_dttm = "2024-01-01" %}
+{% set to_dttm = "2024-12-31" %}
+SELECT *
+FROM tbl
+WHERE dttm_col > '{{ from_dttm }}' AND dttm_col < '{{ to_dttm }}'
+```
+
+:::tip
+When you save a SQL Lab query as a virtual dataset and use it in a chart with time filters,
+the actual filter values will override any defaults or test values you set.

+#### Testing Stories

+Superset uses [@storybook/test-runner](https://storybook.js.org/docs/writing-tests/test-runner) to validate that all stories compile and render without errors. This helps catch broken stories before they're merged.
+
+```bash
+# Run against a running Storybook server (start with `npm run storybook` first)
+npm run test-storybook
+
+# Build static Storybook and test (CI-friendly, no server needed)
