test: Add comprehensive SQL Lab tab state validation tests

Add test suite to validate SQL Lab tab state management and backend
persistence behavior, particularly around the interaction between
frontend-generated string IDs and backend integer ID expectations.

Related to issue #34997: These tests reproduce metadata update
failures when users modify queries in newly created tabs.

Test files:
- sqlLab.tabStateValidation.test.js: 8 tests for tab state edge cases
- sqlLab.immediateBackendPersistence.test.js: 6 tests for persistence

 - **Cypress is last resort** - Actively moving away from Cypress
 - **Use Jest + React Testing Library** for component testing
+- **Use `test()` instead of `describe()`** - Follow [avoid nesting when testing](https://kentcdodds.com/blog/avoid-nesting-when-youre-testing) principles

+## Pull Request Guidelines
+
+**When creating pull requests:**
+
+1. **Read the current PR template**: Always check `.github/PULL_REQUEST_TEMPLATE.md` for the latest format
+2. **Use the template sections**: Include all sections from the template (SUMMARY, BEFORE/AFTER, TESTING INSTRUCTIONS, ADDITIONAL INFORMATION)
+3. **Follow PR title conventions**: Use [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/)
+   - Format: `type(scope): description`
+   - Example: `fix(dashboard): load charts correctly`
+   - Types: `fix`, `feat`, `docs`, `style`, `refactor`, `perf`, `test`, `chore`
+
+**Important**: Always reference the actual template file at `.github/PULL_REQUEST_TEMPLATE.md` instead of using cached content, as the template may be updated over time.
+
 ## Pre-commit Validation
 
 **Use pre-commit hooks for quality validation:**

 ## Next
+- [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.
+- [34782](https://github.com/apache/superset/pull/34782): Dataset exports now include the dataset ID in their file name (similar to charts and dashboards). If managing assets as code, make sure to rename existing dataset YAMLs to include the ID (and avoid duplicated files).
 - [34536](https://github.com/apache/superset/pull/34536): The `ENVIRONMENT_TAG_CONFIG` color values have changed to support only Ant Design semantic colors. Update your `superset_config.py`:
   - Change `"error.base"` to just `"error"` after this PR
   - Change any hex color values to one of: `"success"`, `"processing"`, `"error"`, `"warning"`, `"default"`

docs/README.md

@@ -21,3 +21,183 @@ This is the public documentation site for Superset, built using
 [Docusaurus 3](https://docusaurus.io/). See
 [CONTRIBUTING.md](../CONTRIBUTING.md#documentation) for documentation on
 contributing to documentation.
+
+## Version Management
+
+The Superset documentation site uses Docusaurus versioning with three independent versioned sections:
+
+- **Main Documentation** (`/docs/`) - Core Superset documentation
+- **Developer Portal** (`/developer_portal/`) - Developer guides and tutorials  
+- **Component Playground** (`/components/`) - Interactive component examples (currently disabled)
+
+Each section maintains its own version history and can be versioned independently.
+
+### Creating a New Version
+
+To create a new version for any section, use the Docusaurus version command with the appropriate plugin ID or use our automated scripts:
+
+#### Using Automated Scripts (Required)
+
+**⚠️ Important:** Always use these custom commands instead of the native Docusaurus commands. These scripts ensure that both the Docusaurus versioning system AND the `versions-config.json` file are updated correctly.
+
+```bash
+# Main Documentation
+yarn version:add:docs 1.2.0
+
+# Developer Portal
+yarn version:add:developer_portal 1.2.0
+
+# Component Playground (when enabled)
+yarn version:add:components 1.2.0
+```
+
+**Do NOT use** the native Docusaurus commands directly (`yarn docusaurus docs:version`), as they will:
+- ❌ Create version files but NOT update `versions-config.json`
+- ❌ Cause versions to not appear in dropdown menus
+- ❌ Require manual fixes to synchronize the configuration
+
+### Managing Versions
+
+#### With Automated Scripts
+The automated scripts handle all configuration updates automatically. No manual editing required!
+
+#### Manual Configuration
+If creating versions manually, you'll need to:
+
+1. **Update `versions-config.json`** (or `docusaurus.config.ts` if not using dynamic config):
+   - Add version to `onlyIncludeVersions` array
+   - Add version metadata to `versions` object
+   - Update `lastVersion` if needed
+
+2. **Files Created by Versioning**:
+   When a new version is created, Docusaurus generates:
+   - **Versioned docs folder**: `[section]_versioned_docs/version-X.X.X/`
+   - **Versioned sidebars**: `[section]_versioned_sidebars/version-X.X.X-sidebars.json`
+   - **Versions list**: `[section]_versions.json`
+
+   Note: For main docs, the prefix is omitted (e.g., `versioned_docs/` instead of `docs_versioned_docs/`)
+
+3. **Important**: After adding a version, restart the development server to see changes:
+   ```bash
+   yarn stop
+   yarn start
+   ```
+
+### Removing a Version
+
+#### Using Automated Scripts (Recommended)
+```bash
+# Main Documentation
+yarn version:remove:docs 1.0.0
+
+# Developer Portal
+yarn version:remove:developer_portal 1.0.0
+
+# Component Playground
+yarn version:remove:components 1.0.0
+```
+
+#### Manual Removal
+To manually remove a version:
+
+1. **Delete the version folder** from the appropriate location:
+   - Main docs: `versioned_docs/version-X.X.X/` (no prefix for main)
+   - Developer Portal: `developer_portal_versioned_docs/version-X.X.X/`
+   - Components: `components_versioned_docs/version-X.X.X/`
+
+2. **Delete the version metadata file**:
+   - Main docs: `versioned_sidebars/version-X.X.X-sidebars.json` (no prefix)
+   - Developer Portal: `developer_portal_versioned_sidebars/version-X.X.X-sidebars.json`
+   - Components: `components_versioned_sidebars/version-X.X.X-sidebars.json`
+
+3. **Update the versions list file**:
+   - Main docs: `versions.json`
+   - Developer Portal: `developer_portal_versions.json`
+   - Components: `components_versions.json`
+
+4. **Update configuration**:
+   - If using dynamic config: Update `versions-config.json`
+   - If using static config: Update `docusaurus.config.ts`
+
+5. **Restart the server** to see changes
+
+### Version Configuration Examples
+
+#### Main Documentation (default plugin)
+```typescript
+docs: {
+  includeCurrentVersion: true,
+  lastVersion: 'current',  // Makes /docs/ show Next version
+  onlyIncludeVersions: ['current', '1.1.0', '1.0.0'],
+  versions: {
+    current: {
+      label: 'Next',
+      path: '',  // Empty path for default routing
+      banner: 'unreleased',
+    },
+    '1.1.0': {
+      label: '1.1.0',
+      path: '1.1.0',
+      banner: 'none',
+    },
+  },
+}
+```
+
+#### Developer Portal & Components (custom plugins)
+```typescript
+{
+  id: 'developer_portal',
+  path: 'developer_portal',
+  routeBasePath: 'developer_portal',
+  includeCurrentVersion: true,
+  lastVersion: '1.1.0',  // Default version
+  onlyIncludeVersions: ['current', '1.1.0', '1.0.0'],
+  versions: {
+    current: {
+      label: 'Next',
+      path: 'next',
+      banner: 'unreleased',
+    },
+    '1.1.0': {
+      label: '1.1.0',
+      path: '1.1.0',
+      banner: 'none',
+    },
+  },
+}
+```
+
+### Best Practices
+
+1. **Version naming**: Use semantic versioning (e.g., 1.0.0, 1.1.0, 2.0.0)
+2. **Version banners**: Use `'unreleased'` for development versions, `'none'` for stable releases
+3. **Limit displayed versions**: Use `onlyIncludeVersions` to show only relevant versions
+4. **Test locally**: Always test version changes locally before deploying
+5. **Independent versioning**: Each section can have different version numbers and release cycles
+
+### Troubleshooting
+
+#### Version Not Showing After Creation
+
+If you accidentally used `yarn docusaurus docs:version` instead of `yarn version:add`:
+1. **Problem**: The version files were created but `versions-config.json` wasn't updated
+2. **Solution**: Either:
+   - Revert the changes: `git restore versions.json && rm -rf versioned_docs/ versioned_sidebars/`
+   - Then use the correct command: `yarn version:add:docs <version>`
+
+For other issues:
+- **Restart the server**: Changes to version configuration require a server restart
+- **Check config file**: Ensure `versions-config.json` includes the new version
+- **Verify files exist**: Check that versioned docs folder was created
+
+#### Broken Links in Versioned Documentation
+When creating a new version, links in the documentation are preserved as-is. Common issues:
+- **Cross-section links**: Links between sections (e.g., from developer_portal to docs) need to be version-aware
+- **Absolute vs relative paths**: Use relative paths within the same section
+- **Version-specific URLs**: Update hardcoded URLs to use version variables
+
+To fix broken links:
+1. Use `type: 'doc'` with `docId` for version-aware navigation in navbar
+2. Use relative paths within the same documentation section
+3. Test all versions after creation to identify broken links

+# Bar Chart Component
+
+The Bar Chart component is used to visualize categorical data with rectangular bars.
+
+## Props
+
+| Prop | Type | Default | Description |
+|------|------|---------|-------------|
+| `data` | `array` | `[]` | Array of data objects to visualize |
+| `width` | `number` | `800` | Width of the chart in pixels |
+| `height` | `number` | `600` | Height of the chart in pixels |
+| `xField` | `string` | - | Field name for x-axis values |
+| `yField` | `string` | - | Field name for y-axis values |
+| `colorField` | `string` | - | Field name for color encoding |
+| `colorScheme` | `string` | `'supersetColors'` | Color scheme to use |
+| `showLegend` | `boolean` | `true` | Whether to show the legend |
+| `showGrid` | `boolean` | `true` | Whether to show grid lines |
+| `labelPosition` | `string` | `'top'` | Position of bar labels: 'top', 'middle', 'bottom' |
+
+## Examples
+
+### Basic Bar Chart
+
+```jsx
+import { BarChart } from '@superset-ui/chart-components';
+
+const data = [
+  { category: 'A', value: 10 },
+  { category: 'B', value: 20 },
+  { category: 'C', value: 15 },
+  { category: 'D', value: 25 },
+];
+
+function Example() {
+  return (
+    <BarChart
+      data={data}
+      width={800}
+      height={400}
+      xField="category"
+      yField="value"
+      colorScheme="supersetColors"
+    />
+  );
+}
+```
+
+### Grouped Bar Chart
+
+```jsx
+import { BarChart } from '@superset-ui/chart-components';
+
+const data = [
+  { category: 'A', group: 'Group 1', value: 10 },
+  { category: 'A', group: 'Group 2', value: 15 },
+  { category: 'B', group: 'Group 1', value: 20 },
+  { category: 'B', group: 'Group 2', value: 25 },
+  { category: 'C', group: 'Group 1', value: 15 },
+  { category: 'C', group: 'Group 2', value: 10 },
+];
+
+function Example() {
+  return (
+    <BarChart
+      data={data}
+      width={800}
+      height={400}
+      xField="category"
+      yField="value"
+      colorField="group"
+      colorScheme="supersetColors"
+    />
+  );
+}
+```
+
+## Best Practices
+
+- Use bar charts when comparing quantities across categories
+- Sort bars by value for better readability, unless there's a natural order to the categories
+- Use consistent colors for the same categories across different charts
+- Consider using horizontal bar charts when category labels are long

+
+# Superset Component Library
+
+Welcome to the Apache Superset Component Library documentation. This section provides comprehensive documentation for all the UI components, chart components, and layout components used in Superset.
+
+## What is the Component Library?
+
+The Component Library is a collection of reusable UI components that are used to build the Superset user interface. These components are designed to be consistent, accessible, and easy to use.
+
+## Component Categories
+
+The Component Library is organized into the following categories:
+
+### UI Components
+
+Basic UI components like buttons, inputs, dropdowns, and other form elements.
+
+### Chart Components
+
+Visualization components used to render different types of charts and graphs.
+
+### Layout Components
+
+Components used for page layout, such as containers, grids, and navigation elements.
+
+## Versioning
+
+The Component Library documentation follows its own versioning scheme, independent from the main Superset documentation. This allows us to update the component documentation as the components evolve, without affecting the main documentation.
+
+## Getting Started
+
+Browse the sidebar to explore the different components available in the library. Each component documentation includes:
+
+- Component description and purpose
+- Props and configuration options
+- Usage examples
+- Best practices

+
+### Basic Grid
+
+```jsx
+import { Grid, Row, Col } from '@superset-ui/core';
+
+function Example() {
+  return (
+    <Grid>
+      <Row gutter={16}>
+        <Col span={8}>
+          <div>Column 1</div>
+        </Col>
+        <Col span={8}>
+          <div>Column 2</div>
+        </Col>
+        <Col span={8}>
+          <div>Column 3</div>
+        </Col>
+      </Row>
+    </Grid>
+  );
+}
+```
+
+### Responsive Grid
+
+```jsx
+import { Grid, Row, Col } from '@superset-ui/core';
+
+function Example() {
+  return (
+    <Grid>
+      <Row gutter={[16, 24]}>
+        <Col xs={24} sm={12} md={8} lg={6}>
+          <div>Responsive Column 1</div>
+        </Col>
+        <Col xs={24} sm={12} md={8} lg={6}>
+          <div>Responsive Column 2</div>
+        </Col>
+        <Col xs={24} sm={12} md={8} lg={6}>
+          <div>Responsive Column 3</div>
+        </Col>
+        <Col xs={24} sm={12} md={8} lg={6}>
+          <div>Responsive Column 4</div>
+        </Col>
+      </Row>
+    </Grid>
+  );
+}
+```
+
+## Best Practices
+
+- Use the Grid system for complex layouts that need to be responsive
+- Specify column widths for different screen sizes to ensure proper responsive behavior
+- Use gutters to create appropriate spacing between grid items
+- Keep the grid structure consistent throughout your application
+- Consider using the grid system for dashboard layouts to ensure consistent spacing and alignment

+
+import { StoryExample, StoryWithControls } from '../../src/components/StorybookWrapper';
+import { Button } from '../../../superset-frontend/packages/superset-ui-core/src/components/Button';
+
+# Button Component
+
+The Button component is a fundamental UI element used throughout Superset for user interactions.
+
+## Basic Usage
+
+The default button with primary styling:
+<StoryExample
+  component={() => (
+    <Button buttonStyle="primary" onClick={() => console.log('Clicked!')}>
+      Click Me
+    </Button>
+  )}
+/>
+
+## Interactive Example
+
+<StoryWithControls
+  component={({ buttonStyle, buttonSize, label, disabled }) => (
+    <Button
+      buttonStyle={buttonStyle}
+      buttonSize={buttonSize}
+      disabled={disabled}
+      onClick={() => console.log('Clicked!')}
+    >
+      {label}
+    </Button>
+  )}
+  props={{
+    buttonStyle: 'primary',
+    buttonSize: 'default',
+    label: 'Click Me',
+    disabled: false
+  }}
+  controls={[
+    {
+      name: 'buttonStyle',
+      label: 'Button Style',
+      type: 'select',
+      options: ['primary', 'secondary', 'tertiary', 'success', 'warning', 'danger', 'default', 'link', 'dashed']
+    },
+    {
+      name: 'buttonSize',
+      label: 'Button Size',
+      type: 'select',
+      options: ['default', 'small', 'xsmall']
+    },
+    {
+      name: 'label',
+      label: 'Button Text',
+      type: 'text'
+    },
+    {
+      name: 'disabled',
+      label: 'Disabled',
+      type: 'boolean'
+    }
+  ]}
+/>
+
+## Props
+
+| Prop | Type | Default | Description |
+|------|------|---------|-------------|
+| `buttonStyle` | `'primary' \| 'secondary' \| 'tertiary' \| 'success' \| 'warning' \| 'danger' \| 'default' \| 'link' \| 'dashed'` | `'default'` | Button style |
+| `buttonSize` | `'default' \| 'small' \| 'xsmall'` | `'default'` | Button size |
+| `disabled` | `boolean` | `false` | Whether the button is disabled |
+| `cta` | `boolean` | `false` | Whether the button is a call-to-action button |
+| `tooltip` | `ReactNode` | - | Tooltip content |
+| `placement` | `TooltipProps['placement']` | - | Tooltip placement |
+| `onClick` | `function` | - | Callback when button is clicked |
+| `href` | `string` | - | Turns button into an anchor link |
+| `target` | `string` | - | Target attribute for anchor links |
+
+## Usage
+
+```jsx
+import Button from 'src/components/Button';
+
+function MyComponent() {
+  return (
+    <Button
+      buttonStyle="primary"
+      onClick={() => console.log('Button clicked')}
+    >
+      Click Me
+    </Button>
+  );
+}
+```
+
+## Button Styles
+
+Superset provides a variety of button styles for different purposes:
+
+- **Primary**: Used for primary actions
+- **Secondary**: Used for secondary actions
+- **Tertiary**: Used for less important actions
+- **Success**: Used for successful or confirming actions
+- **Warning**: Used for actions that require caution
+- **Danger**: Used for destructive actions
+- **Link**: Used for navigation
+- **Dashed**: Used for adding new items or features
+
+## Button Sizes
+
+Buttons come in three sizes:
+
+- **Default**: Standard size for most use cases
+- **Small**: Compact size for tight spaces
+- **XSmall**: Extra small size for very limited spaces
+
+## Best Practices
+
+- Use primary buttons for the main action in a form or page
+- Use secondary buttons for alternative actions
+- Use danger buttons for destructive actions
+- Limit the number of primary buttons on a page to avoid confusion
+- Use consistent button styles throughout your application
+- Add tooltips to buttons when their purpose might not be immediately clear

+import {
+  Button,
+  Select,
+  Input,
+  Table,
+  Modal,
+  Alert,
+  Tabs,
+  Card,
+  Dropdown,
+  Menu,
+  Tooltip,
+  Icon,
+  // ... many more
+} from '@apache-superset/core';
+```
+
+### Example Component Usage
+
+```typescript
+import { Button, Alert } from '@apache-superset/core';
+
+function MyExtensionPanel() {
+  return (
+    <div>
+      <Alert
+        message="Extension Loaded"
+        description="Your extension is ready to use"
+        type="success"
+      />
+      <Button
+        type="primary"
+        onClick={() => console.log('Clicked!')}
+      >
+        Execute Action
+      </Button>
+    </div>
+  );
+}
+```
+
+## Storage API
+
+Provides persistent storage for extension data.
+
+### Local Storage
+
+```typescript
+// Store data
+storage.local.set(key: string, value: any): Promise<void>
+
+// Retrieve data
+storage.local.get(key: string): Promise<any>
+
+// Remove data
+storage.local.remove(key: string): Promise<void>
+
+// Clear all extension data
+storage.local.clear(): Promise<void>
+```
+
+### Workspace Storage
+
+Workspace storage is shared across all users for collaborative features.
+
+```typescript
+storage.workspace.set(key: string, value: any): Promise<void>
+storage.workspace.get(key: string): Promise<any>
+storage.workspace.remove(key: string): Promise<void>
+```
+
+## Network API
+
+Utilities for making API calls to Superset.
+
+### fetch
+
+Enhanced fetch with CSRF token handling.
+
+```typescript
+network.fetch(url: string, options?: RequestInit): Promise<Response>
+```
+
+### API Client
+
+Type-safe API client for Superset endpoints.
+
+```typescript
+// Get chart data
+network.api.charts.get(id: number): Promise<Chart>
+
+// Query database
+network.api.sqlLab.execute(
+  databaseId: number,
+  query: string
+): Promise<QueryResult>
+
+// Get datasets
+network.api.datasets.list(): Promise<Dataset[]>
+```
+
+## Utility Functions
+
+### Formatting
+
+```typescript
+// Format numbers
+utils.formatNumber(value: number, format?: string): string
+
+// Format dates
+utils.formatDate(date: Date, format?: string): string
+
+// Format SQL
+utils.formatSQL(sql: string): string
+```
+
+### Validation
+
+```typescript
+// Validate SQL syntax
+utils.validateSQL(sql: string): ValidationResult
+
+// Check if valid database ID
+utils.isValidDatabaseId(id: any): boolean
+```
+
+## TypeScript Types
+
+Import common types for type safety:
+
+```typescript
+import type {
+  Database,
+  Dataset,
+  Chart,
+  Dashboard,
+  Query,
+  QueryResult,
+  Tab,
+  Panel,
+  User,
+  Role,
+  Permission,
+  ExtensionContext,
+  Disposable,
+  Event,
+  // ... more types
+} from '@apache-superset/core';
+```
+
+## Extension Context
+
+The context object passed to your extension's `activate` function:
+
+```typescript
+interface ExtensionContext {
+  // Subscription management
+  subscriptions: Disposable[];
+
+  // Extension metadata
+  extensionId: string;
+  extensionPath: string;
+
+  // API namespaces
+  core: CoreAPI;
+  commands: CommandsAPI;
+  sqlLab: SqlLabAPI;
+  authentication: AuthenticationAPI;
+  extensions: ExtensionsAPI;
+  storage: StorageAPI;
+  network: NetworkAPI;
+  utils: UtilsAPI;
+
+  // Logging
+  logger: Logger;
+}
+```
+
+## Event Handling
+
+Events follow the VS Code pattern with subscribe/dispose:
+
+```typescript
+// Subscribe to event
+const disposable = sqlLab.onDidQueryRun((result) => {
+  // Handle event
+});
+
+// Dispose when done
+disposable.dispose();
+
+// Or add to context for automatic cleanup
+context.subscriptions.push(disposable);
+```
+
+## Best Practices
+
+1. **Always dispose subscriptions** to prevent memory leaks
+2. **Use TypeScript** for better IDE support and type safety
+3. **Handle errors gracefully** with try-catch blocks
+4. **Check permissions** before sensitive operations
+5. **Use provided UI components** for consistency
+6. **Cache API responses** when appropriate
+7. **Validate user input** before processing
+
+## Version Compatibility
+
+The frontend API follows semantic versioning:
+
+- **Major version**: Breaking changes
+- **Minor version**: New features, backward compatible
+- **Patch version**: Bug fixes
+
+Check compatibility in your `extension.json`:
+
+```json
+{
+  "engines": {
+    "@apache-superset/core": "^1.0.0"
+  }
+}
+```

+
+# Extension Architecture Overview
+
+The Superset extension architecture is designed to be modular, secure, and performant. This document provides a comprehensive overview of how extensions work and interact with the Superset host application.
+
+## Core Principles
+
+### 1. Lean Core
+Superset's core remains minimal, with features delegated to extensions wherever possible. Built-in features use the same APIs as external extensions, ensuring API quality through dogfooding.
+
+### 2. Explicit Contribution Points
+All extension points are clearly defined and documented. Extensions declare their capabilities in metadata files, enabling predictable lifecycle management.
+
+### 3. Versioned APIs
+Public interfaces follow semantic versioning, ensuring backward compatibility and safe evolution of the platform.
+
+### 4. Lazy Loading
+Extensions load only when needed, minimizing performance impact and resource consumption.
+
+### 5. Composability
+Architecture patterns and APIs are reusable across different Superset modules, promoting consistency.
+
+### 6. Community-Driven
+The system evolves based on real-world feedback, with new extension points added as needs emerge.
+

+    Frontend --> FrontendCore
+    Backend --> BackendCore
+    CLI --> Bundle
+```
+
+## Key Components
+
+### Host Application
+
+The Superset host application provides:
+
+- **Extension APIs**: Well-defined interfaces for extensions to interact with Superset
+- **Extension Manager**: Handles lifecycle, activation, and deactivation
+- **Module Loader**: Dynamically loads extension code using Webpack Module Federation
+- **Security Context**: Manages permissions and sandboxing for extensions
+
+### Core Packages
+
+#### @apache-superset/core (Frontend)
+- Shared UI components and utilities
+- TypeScript type definitions
+- Frontend API implementations
+- Event system and command registry
+
+#### apache-superset-core (Backend)
+- Python base classes and utilities
+- Database access APIs
+- Security and permission helpers
+- REST API registration
+
+#### apache-superset-extensions-cli
+- Project scaffolding
+- Build and bundling tools
+- Development server
+- Package management
+
+### Extension Structure
+
+Each extension consists of:
+
+- **Metadata** (`extension.json`): Declares capabilities and requirements
+- **Frontend**: React components and TypeScript code
+- **Backend**: Python modules and API endpoints
+- **Assets**: Styles, images, and other resources
+- **Bundle** (`.supx`): Packaged distribution format
+
+## Module Federation
+
+Extensions use Webpack Module Federation for dynamic loading:
+
+```javascript
+// Extension webpack.config.js
+new ModuleFederationPlugin({
+  name: 'my_extension',
+  filename: 'remoteEntry.[contenthash].js',
+  exposes: {
+    './index': './src/index.tsx',
+  },
+  externals: {
+    '@apache-superset/core': 'superset',
+  },
+  shared: {
+    react: { singleton: true },
+    'react-dom': { singleton: true },
+  }
+})
+```
+
+This allows:
+- **Independent builds**: Extensions compile separately from Superset
+- **Shared dependencies**: Common libraries like React aren't duplicated
+- **Dynamic loading**: Extensions load at runtime without rebuilding Superset
+- **Version compatibility**: Extensions declare compatible core versions
+
+## Extension Lifecycle
+
+### 1. Registration
+```typescript
+// Extension registered with host
+extensionManager.register({
+  name: 'my-extension',
+  version: '1.0.0',
+  manifest: manifestData
+});
+```
+
+### 2. Activation
+```typescript
+// activate() called when extension loads
+export function activate(context: ExtensionContext) {
+  // Register contributions
+  const disposables = [];
+
+  // Add panel
+  disposables.push(
+    context.core.registerView('my-panel', MyPanel)
+  );
+
+  // Register command
+  disposables.push(
+    context.commands.registerCommand('my-command', {
+      execute: () => { /* ... */ }
+    })
+  );
+
+  // Store for cleanup
+  context.subscriptions.push(...disposables);
+}
+```
+
+### 3. Runtime
+- Extension responds to events
+- Provides UI components when requested
+- Executes commands when triggered
+- Accesses APIs as needed
+
+### 4. Deactivation
+```typescript
+// Automatic cleanup of registered items
+export function deactivate() {
+  // context.subscriptions automatically disposed
+  // Additional cleanup if needed
+}
+```
+
+## Contribution Types
+
+### Views
+Extensions can add panels and UI components:
+
+```json
+{
+  "views": {
+    "sqllab.panels": [{
+      "id": "my-panel",
+      "name": "My Panel",
+      "icon": "ToolOutlined"
+    }]
+  }
+}
+```
+
+### Commands
+Define executable actions:
+
+```json
+{
+  "commands": [{
+    "command": "my-extension.run",
+    "title": "Run Analysis",
+    "icon": "PlayCircleOutlined"
+  }]
+}
+```
+
+### Menus
+Add items to existing menus:
+
+```json
+{
+  "menus": {
+    "sqllab.editor": {
+      "primary": [{
+        "command": "my-extension.run",
+        "when": "editorHasSelection"
+      }]
+    }
+  }
+}
+```
+
+### API Endpoints
+Register backend REST endpoints:
+
+```python
+from superset_core.api import rest_api
+
+@rest_api.route('/my-endpoint')
+def my_endpoint():
+    return {'data': 'value'}
+```
+
+## Security Model
+
+### Permissions
+- Extensions run with user's permissions
+- No elevation of privileges
+- Access controlled by Superset's RBAC
+
+### Sandboxing
+- Frontend code runs in browser context
+- Backend code runs in Python process
+- Future: Optional sandboxed execution
+
+### Validation
+- Manifest validation on upload
+- Signature verification (future)
+- Dependency scanning
+
+## Performance Considerations
+
+### Lazy Loading
+- Extensions load only when features are accessed
+- Code splitting for large extensions
+- Cached after first load
+
+### Bundle Optimization
+- Tree shaking removes unused code
+- Minification reduces size
+- Compression for network transfer
+
+### Resource Management
+- Automatic cleanup on deactivation
+- Memory leak prevention
+- Event listener management
+
+## Development vs Production
+
+### Development Mode
+```python
+# superset_config.py
+ENABLE_EXTENSIONS = True
+LOCAL_EXTENSIONS = ['/path/to/extension']
+```
+- Hot reloading
+- Source maps
+- Debug logging
+
+### Production Mode
+- Optimized bundles
+- Cached assets
+- Performance monitoring
+
+## Future Enhancements
+
+### Planned Features
+- Enhanced sandboxing
+- Extension marketplace
+- Inter-extension communication
+- Theme contributions
+- Chart type extensions
+
+### API Expansion
+- Dashboard extensions
+- Database connector API
+- Security provider interface
+- Workflow automation
+
+## Best Practices
+
+### Do's
+- ✅ Use TypeScript for type safety
+- ✅ Follow semantic versioning
+- ✅ Handle errors gracefully
+- ✅ Clean up resources properly
+- ✅ Document your extension
+
+### Don'ts
+- ❌ Access private APIs
+- ❌ Modify global state directly
+- ❌ Block the main thread
+- ❌ Store sensitive data insecurely
+- ❌ Assume API stability in 0.x versions

+## Configuration
+
+### Project Configuration
+
+The CLI reads configuration from multiple sources:
+
+1. **extension.json** - Extension metadata
+2. **package.json** - Frontend dependencies
+3. **pyproject.toml** - Backend configuration
+4. **.extensionrc** - CLI-specific settings
+
+### .extensionrc Example
+
+```json
+{
+  "dev": {
+    "port": 9001,
+    "host": "localhost",
+    "autoReload": true
+  },
+  "build": {
+    "mode": "production",
+    "sourceMaps": false,
+    "optimization": true
+  },
+  "test": {
+    "coverage": true,
+    "threshold": {
+      "statements": 80,
+      "branches": 70,
+      "functions": 80,
+      "lines": 80
+    }
+  }
+}
+```
+
+## Templates
+
+### Available Templates
+
+- **basic**: Simple extension with frontend only
+- **full-stack**: Frontend and backend components
+- **sql-panel**: SQL Lab panel extension
+- **api-only**: Backend API extension
+- **chart-plugin**: Custom chart visualization
+
+### Using Templates
+
+```bash
+# Use specific template
+superset-extensions init my-chart --template chart-plugin
+
+# List available templates
+superset-extensions init --list-templates
+```
+
+### Custom Templates
+
+Create custom templates in `~/.superset-extensions/templates/`:
+
+```
+~/.superset-extensions/templates/
+└── my-template/
+    ├── template.json
+    └── files/
+        └── ... template files ...
+```
+
+## Development Workflow
+
+### 1. Create Extension
+
+```bash
+superset-extensions init awesome-feature
+cd awesome-feature
+```
+
+### 2. Install Dependencies
+
+```bash
+# Frontend
+cd frontend && npm install
+
+# Backend (if applicable)
+cd ../backend && pip install -r requirements.txt
+```
+
+### 3. Configure Superset
+
+```python
+# superset_config.py
+ENABLE_EXTENSIONS = True
+LOCAL_EXTENSIONS = [
+    "/path/to/awesome-feature"
+]
+```
+
+### 4. Start Development
+
+```bash
+# Terminal 1: Extension dev server
+superset-extensions dev
+
+# Terminal 2: Superset
+superset run -p 8088 --reload
+```
+
+### 5. Test Changes
+
+Make changes to your code and see them reflected immediately in Superset.
+
+### 6. Build and Package
+
+```bash
+# Validate
+superset-extensions validate
+
+# Test
+superset-extensions test
+
+# Build
+superset-extensions build --mode production
+
+# Bundle
+superset-extensions bundle
+```
+
+### 7. Deploy
+
+Upload the `.supx` file to your Superset instance.
+
+## Environment Variables
+
+The CLI respects these environment variables:
+
+- `SUPERSET_EXTENSIONS_DEV_PORT`: Development server port
+- `SUPERSET_EXTENSIONS_DEV_HOST`: Development server host
+- `SUPERSET_BASE_URL`: Superset instance URL
+- `NODE_ENV`: Node environment (development/production)
+- `PYTHONPATH`: Python module search path
+
+## Troubleshooting
+
+### Common Issues
+
+#### Port Already in Use
+
+```bash
+# Use different port
+superset-extensions dev --port 9002
+```
+
+#### Module Federation Errors
+
+```bash
+# Rebuild with clean cache
+rm -rf dist/ node_modules/.cache
+superset-extensions build
+```
+
+#### Python Import Errors
+
+```bash
+# Ensure virtual environment is activated
+source venv/bin/activate
+superset-extensions dev
+```
+
+### Debug Mode
+
+Enable verbose output for troubleshooting:
+
+```bash
+# Verbose output
+superset-extensions dev --verbose
+
+# Debug webpack
+DEBUG=webpack:* superset-extensions build
+```
+
+## Best Practices
+
+1. **Version Control**: Commit `extension.json` but not `dist/`
+2. **Dependencies**: Pin versions in package.json
+3. **Testing**: Write tests for critical functionality
+4. **Documentation**: Keep README.md updated
+5. **Validation**: Run validate before bundling
+6. **Semantic Versioning**: Follow semver for releases
+
+## Advanced Usage
+
+### Custom Webpack Configuration
+
+Extend the default webpack config:
+
+```javascript
+// webpack.config.js
+const baseConfig = require('./webpack.base.config');
+
+module.exports = {
+  ...baseConfig,
+  // Custom modifications
+  resolve: {
+    ...baseConfig.resolve,
+    alias: {
+      '@': path.resolve(__dirname, 'src'),
+    },
+  },
+};
+```
+
+### CI/CD Integration
+
+```yaml
+# .github/workflows/extension.yml
+name: Extension CI
+
+on: [push, pull_request]
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+      - uses: actions/setup-node@v2

+# Extension Examples
+
+Learn from real-world extension implementations that showcase different capabilities of the Superset extension system.
+
+## Dataset References Panel
+
+A SQL Lab panel that analyzes queries and displays information about referenced tables.
+
+### Features
+- Parses SQL to extract table references
+- Shows table owners and permissions
+- Displays last partition information
+- Provides row count estimates
+
+### Key Implementation
+
+```typescript
+// Parse SQL and extract tables
+function extractTables(sql: string): TableReference[] {
+  const tables = [];
+  const tableRegex = /FROM\s+(\w+\.?\w+)/gi;
+  let match;
+
+  while ((match = tableRegex.exec(sql)) !== null) {
+    tables.push({
+      schema: match[1].split('.')[0],
+      table: match[1].split('.')[1] || match[1],
+    });
+  }
+
+  return tables;
+}
+
+// Register panel
+export function activate(context: ExtensionContext) {
+  const panel = context.core.registerView('dataset-references.panel', () => (
+    <DatasetReferencesPanel />
+  ));
+
+  // Listen for query changes
+  const listener = context.sqlLab.onDidChangeEditorContent((content) => {
+    const tables = extractTables(content);
+    updatePanelWithTables(tables);
+  });
+
+  context.subscriptions.push(panel, listener);
+}
+```
+
+### Manifest

+
+# Getting Started with Extensions
+
+This guide will walk you through creating, developing, and deploying your first Superset extension.
+
+## Prerequisites
+
+Before you begin, make sure you have:
+
+- **Node.js 16+** and npm/yarn installed
+- **Python 3.9+** and pip installed  
+- **Superset** running locally or access to a Superset instance
+- **Git** for version control
+- Basic knowledge of React and TypeScript
+
+## Quick Start
+
+### 1. Install the CLI
+
+First, install the Superset Extensions CLI globally:
+
+```bash
+pip install apache-superset-extensions-cli
+```
+
+### 2. Create Your First Extension
+
+Use the CLI to scaffold a new extension project:
+
+```bash
+superset-extensions init my-first-extension
+cd my-first-extension
+```
+
+This creates the following structure:
+
+```
+my-first-extension/
+├── extension.json          # Extension metadata
+├── frontend/              # Frontend code
+│   ├── src/
+│   │   └── index.tsx     # Main entry point
+│   ├── package.json
+│   └── webpack.config.js
+├── backend/              # Backend code (optional)
+│   ├── src/
+│   └── requirements.txt
+└── README.md
+```
+
+### 3. Configure Your Extension
+
+Edit `extension.json` to define your extension's capabilities:
+
+```json
+{
+  "name": "my-first-extension",
+  "version": "1.0.0",
+  "description": "My first Superset extension",
+  "author": "Your Name",
+  "frontend": {
+    "contributions": {
+      "views": {
+        "sqllab.panels": [
+          {
+            "id": "my-extension.main",
+            "name": "My Panel",
+            "icon": "ToolOutlined"
+          }
+        ]
+      }
+    }
+  }
+}
+```
+
+### 4. Develop Your Extension
+
+Edit `frontend/src/index.tsx` to implement your extension:
+
+```typescript
+import React from 'react';
+import { ExtensionContext } from '@apache-superset/core';
+
+export function activate(context: ExtensionContext) {
+  // Register your panel component
+  const panel = context.core.registerView('my-extension.main', () => (
+    <div style={{ padding: 20 }}>
+      <h2>Hello from My Extension!</h2>
+      <p>This is my first Superset extension.</p>
+    </div>
+  ));
+
+  // Clean up on deactivation
+  context.subscriptions.push(panel);
+}
+
+export function deactivate() {
+  // Cleanup code if needed
+}
+```
+
+### 5. Test Locally
+
+Enable development mode in your Superset configuration:
+
+```python
+# superset_config.py
+ENABLE_EXTENSIONS = True
+LOCAL_EXTENSIONS = [
+    "/path/to/my-first-extension"
+]
+```
+
+Run the development server:
+
+```bash
+# In your extension directory
+superset-extensions dev
+
+# In a separate terminal, start Superset
+superset run -p 8088 --with-threads --reload
+```
+
+Your extension will now appear in SQL Lab!
+
+### 6. Build and Package
+
+When ready to distribute your extension:
+
+```bash
+superset-extensions build
+superset-extensions bundle
+```
+
+This creates a `my-first-extension-1.0.0.supx` file that can be uploaded to any Superset instance.
+
+### 7. Deploy
+
+Upload your extension via the Superset UI or API:
+
+```bash
+curl -X POST http://localhost:8088/api/v1/extensions/import/ \
+  -H "Authorization: Bearer YOUR_TOKEN" \
+  -F "file=@my-first-extension-1.0.0.supx"
+```
+
+## What's Next?
+
+Now that you have a basic extension working, explore:
+
+- [Extension Architecture](../architecture/overview) - Understand how extensions work
+- [API Reference](../api/frontend) - Learn about available APIs
+- [Examples](../examples) - See more complex extension examples
+- [Best Practices](./best-practices) - Learn extension development best practices
+
+## Common Patterns
+
+### Adding a SQL Lab Panel
+
+```typescript
+const panel = context.core.registerView('my-extension.panel', () => (
+  <MyPanelComponent />
+));
+```
+
+### Registering Commands
+
+```typescript
+const command = context.commands.registerCommand('my-extension.run', {
+  title: 'Run My Command',
+  execute: () => {
+    // Command logic
+  }
+});
+```
+
+### Listening to Events
+
+```typescript
+const listener = context.sqlLab.onDidQueryRun((query) => {
+  console.log('Query executed:', query);
+});
+```
+
+### Adding Menu Items
+
+```json
+{
+  "menus": {
+    "sqllab.editor": {
+      "primary": [{
+        "command": "my-extension.run",
+        "when": "editorHasSelection"
+      }]
+    }
+  }
+}
+```
+
+## Troubleshooting
+
+### Extension Not Loading
+
+- Ensure `ENABLE_EXTENSIONS = True` in your config
+- Check the browser console for errors
+- Verify the extension path in `LOCAL_EXTENSIONS`
+
+### Module Not Found Errors
+
+- Run `npm install` in the frontend directory
+- Check that `@apache-superset/core` is properly externalized
+
+### Build Failures
+
+- Ensure all dependencies are installed
+- Check webpack.config.js for proper Module Federation setup
+- Verify extension.json is valid JSON
+
+## Get Help
+

+# Superset Developer Portal
+
+Welcome to the Apache Superset Developer Portal! This is your comprehensive guide to extending and customizing Superset through our new extension architecture.
+
+## What are Superset Extensions?
+
+Superset Extensions provide a powerful way to enhance and customize Apache Superset without modifying the core codebase. Following the successful model pioneered by VS Code, our extension architecture enables developers to:
+
+- **Add custom features** to SQL Lab and other Superset modules
+- **Create reusable components** that can be shared across organizations
+- **Integrate external tools** and services seamlessly
+- **Customize workflows** to match your team's specific needs
+
+## Why Extensions?
+
+As Superset has grown, we've recognized the need for a more modular architecture that allows:
+
+- **Innovation without fragmentation** - Build features without forking the codebase
+- **Community-driven development** - Share and reuse extensions across organizations
+- **Stable APIs** - Develop against versioned, well-documented interfaces
+- **Rapid iteration** - Deploy custom features without waiting for core releases
+
+## Key Features
+
+### 🎯 Well-Defined Extension Points
+
+Extensions can contribute to specific areas of Superset:
+- SQL Lab panels (left, right, bottom, editor)
+- Custom commands and menu items
+- Status bar components
+- API endpoints and backend functionality
+
+### 🔧 Modern Development Experience
+
+- **CLI tools** for scaffolding, building, and packaging
+- **Hot reloading** during development
+- **TypeScript support** with full type safety
+- **Module Federation** for dynamic loading
+
+### 📦 Simple Distribution
+
+- Package extensions as `.supx` files
+- Upload via REST API or UI
+- Automatic activation and lifecycle management
+- Version compatibility checking
+
+## Getting Started
+
+Ready to build your first extension? Check out our [Getting Started Guide](./getting-started) to:
+
+1. Set up your development environment
+2. Create your first extension
+3. Test it locally
+4. Package and deploy it
+
+## Architecture Overview
+
+Our extension architecture is built on several key principles:
+
+- **Lean Core**: Keep Superset's core minimal and delegate features to extensions
+- **Explicit APIs**: Clear, versioned interfaces for extension interactions
+- **Lazy Loading**: Extensions load only when needed for optimal performance
+- **Security First**: Extensions run with appropriate permissions and sandboxing
+
+Learn more in our [Architecture Documentation](./architecture/overview).
+
+## Current Status
+
+The extension architecture is currently in active development. The initial focus is on SQL Lab extensions, with plans to expand to:
+
+- Dashboard extensions
+- Chart plugins (enhanced from current system)
+- Database connectors
+- Security providers
+
+## Example: Dataset References Extension
+
+See the extension system in action with our Dataset References example, which adds a SQL Lab panel showing:
+
+- Tables referenced in queries
+- Table owners for permission requests  
+- Last available partitions
+- Estimated row counts
+
+## Join the Community
+
+- **Contribute**: Help shape the future of Superset extensions
+- **Share**: Publish your extensions for others to use
+- **Learn**: Explore extensions built by the community

+You'll need to extend the Superset image to include a headless browser. Your options include:
+- Use Playwright with Chrome: this is the recommended approach as of version >=4.1.x. A working example of a Dockerfile that installs these tools is provided under “Building your own production Docker image” on the [Docker Builds](/docs/installation/docker-builds#building-your-own-production-docker-image) page. Read the code comments there as you'll also need to change a feature flag in your config.
+- Use Firefox: you'll need to install geckodriver and Firefox.
+- Use Chrome without Playwright: you'll need to install Chrome and set the value of `WEBDRIVER_TYPE` to `"chrome"` in your `superset_config.py`.
 
-Note: All the components required (Firefox headless browser, Redis, Postgres db, celery worker and celery beat) are present in the *dev* docker image if you are following [Installing Superset Locally](/docs/installation/docker-compose/).
-All you need to do is add the required config variables described in this guide (See `Detailed Config`).
+In Superset versions <=4.0x, users installed Firefox or Chrome and that was documented here.
 
-If you are running a non-dev docker image, e.g., a stable release like `apache/superset:3.1.0`, that image does not include a headless browser.  Only the `superset_worker` container needs this headless browser to browse to the target chart or dashboard.
-You can either install and configure the headless browser - see "Custom Dockerfile" section below - or when deploying via `docker compose`, modify your `docker-compose.yml` file to use a dev image for the worker container and a stable release image for the `superset_app` container.
-
-*Note*: In this context, a "dev image" is the same application software as its corresponding non-dev image, just bundled with additional tools.  So an image like `3.1.0-dev` is identical to `3.1.0` when it comes to stability, functionality, and running in production.  The actual "in-development" versions of Superset - cutting-edge and unstable - are not tagged with version numbers on Docker Hub and will display version `0.0.0-dev` within the Superset UI.

+## ECharts Configuration Overrides
+
+:::note
+Available since Superset 6.0
+:::
+
+Superset provides fine-grained control over ECharts visualizations through theme-level configuration overrides. This allows you to customize the appearance and behavior of all ECharts-based charts without modifying individual chart configurations.
+
+### Global ECharts Overrides
+
+Apply settings to all ECharts visualizations using `echartsOptionsOverrides`:
+
+```python
+THEME_DEFAULT = {
+    "token": {
+        "colorPrimary": "#2893B3",
+        # ... other Ant Design tokens
+    },
+    "echartsOptionsOverrides": {
+        "grid": {
+            "left": "10%",
+            "right": "10%",
+            "top": "15%",
+            "bottom": "15%"
+        },
+        "tooltip": {
+            "backgroundColor": "rgba(0, 0, 0, 0.8)",
+            "borderColor": "#ccc",
+            "textStyle": {
+                "color": "#fff"
+            }
+        },
+        "legend": {
+            "textStyle": {
+                "fontSize": 14,
+                "fontWeight": "bold"
+            }
+        }
+    }
+}
+```
+
+### Chart-Specific Overrides
+
+Target specific chart types using `echartsOptionsOverridesByChartType`:
+
+```python
+THEME_DEFAULT = {
+    "token": {
+        "colorPrimary": "#2893B3",
+        # ... other tokens
+    },
+    "echartsOptionsOverridesByChartType": {
+        "echarts_pie": {
+            "legend": {
+                "orient": "vertical",
+                "right": 10,
+                "top": "center"
+            }
+        },
+        "echarts_timeseries": {
+            "xAxis": {
+                "axisLabel": {
+                    "rotate": 45,
+                    "fontSize": 12
+                }
+            },
+            "dataZoom": [{
+                "type": "slider",
+                "show": True,
+                "start": 0,
+                "end": 100
+            }]
+        },
+        "echarts_bubble": {
+            "grid": {
+                "left": "15%",
+                "bottom": "20%"
+            }
+        }
+    }
+}
+```
+
+### UI Configuration
+
+You can also configure ECharts overrides through the theme CRUD interface:
+
+```json
+{
+  "token": {
+    "colorPrimary": "#2893B3"
+  },
+  "echartsOptionsOverrides": {
+    "grid": {
+      "left": "10%",
+      "right": "10%"
+    },
+    "tooltip": {
+      "backgroundColor": "rgba(0, 0, 0, 0.8)"
+    }
+  },
+  "echartsOptionsOverridesByChartType": {
+    "echarts_pie": {
+      "legend": {
+        "orient": "vertical",
+        "right": 10
+      }
+    }
+  }
+}
+```
+
+### Override Precedence
+
+The system applies overrides in the following order (last wins):
+
+1. **Base ECharts theme** - Default Superset styling
+2. **Plugin options** - Chart-specific configurations
+3. **Global overrides** - `echartsOptionsOverrides`
+4. **Chart-specific overrides** - `echartsOptionsOverridesByChartType[chartType]`
+
+This ensures chart-specific overrides take precedence over global ones.
+
+### Common Chart Types
+
+Available chart types for `echartsOptionsOverridesByChartType`:
+
+- `echarts_timeseries` - Time series/line charts
+- `echarts_pie` - Pie and donut charts
+- `echarts_bubble` - Bubble/scatter charts
+- `echarts_funnel` - Funnel charts
+- `echarts_gauge` - Gauge charts
+- `echarts_radar` - Radar charts
+- `echarts_boxplot` - Box plot charts
+- `echarts_treemap` - Treemap charts
+- `echarts_sunburst` - Sunburst charts
+- `echarts_graph` - Network/graph charts
+- `echarts_sankey` - Sankey diagrams
+- `echarts_heatmap` - Heatmaps
+- `echarts_mixed_timeseries` - Mixed time series
+
+### Best Practices
+
+1. **Start with global overrides** for consistent styling across all charts
+2. **Use chart-specific overrides** for unique requirements per visualization type
+3. **Test thoroughly** as overrides use deep merge - nested objects are combined, but arrays are completely replaced
+4. **Document your overrides** to help team members understand custom styling
+5. **Consider performance** - complex overrides may impact chart rendering speed
+
+### Example: Corporate Branding
+
+```python
+# Complete corporate theme with ECharts customization
+THEME_DEFAULT = {
+    "token": {
+        "colorPrimary": "#1B4D3E",
+        "fontFamily": "Corporate Sans, Arial, sans-serif"
+    },
+    "echartsOptionsOverrides": {
+        "grid": {
+            "left": "8%",
+            "right": "8%",
+            "top": "12%",
+            "bottom": "12%"
+        },
+        "textStyle": {
+            "fontFamily": "Corporate Sans, Arial, sans-serif"
+        },
+        "title": {
+            "textStyle": {
+                "color": "#1B4D3E",
+                "fontSize": 18,
+                "fontWeight": "bold"
+            }
+        }
+    },
+    "echartsOptionsOverridesByChartType": {
+        "echarts_timeseries": {
+            "xAxis": {
+                "axisLabel": {
+                    "color": "#666",
+                    "fontSize": 11
+                }
+            }
+        },
+        "echarts_pie": {
+            "legend": {
+                "textStyle": {
+                    "fontSize": 12
+                },
+                "itemGap": 20
+            }
+        }
+    }
+}
+```
+
+This feature provides powerful theming capabilities while maintaining the flexibility of ECharts' extensive configuration options.

+#### Known Issues and Workarounds
+
+**Jest Test Hanging (MessageChannel Issue)**
+
+If Jest tests hang with "Jest did not exit one second after the test run has completed", this is likely due to the MessageChannel issue from rc-overflow (Ant Design v5 components).
+
+**Root Cause**: `rc-overflow@1.4.1` creates MessageChannel handles for responsive overflow detection that remain open after test completion.
+
+**Current Workaround**: MessageChannel is mocked as undefined in `spec/helpers/jsDomWithFetchAPI.ts`, forcing rc-overflow to use requestAnimationFrame fallback.
+
+**To verify if still needed**: Remove the MessageChannel mocking lines and run `npm test -- --shard=4/8`. If tests hang, the workaround is still required.
+
+**Future removal conditions**: This workaround can be removed when:
+- rc-overflow updates to properly clean up MessagePorts in test environments
+- Jest updates to handle MessageChannel/MessagePort cleanup better
+- Ant Design switches away from rc-overflow
+- We switch away from Ant Design v5
+
+**See**: [PR #34871](https://github.com/apache/superset/pull/34871) for full technical details.
