This comprehensive architectural transformation removes all static theme imports
(supersetTheme, themeObject) across the entire codebase, replacing them with
proper dynamic theme access patterns that support real-time theme switching.
## What Changed
**Static Exports Eliminated:**
- Removed `supersetTheme` and `themeObject` exports from core theme module
- Eliminated static theme dependencies across 47 files
- Updated ESLint rules to reflect removed exports
**Dynamic Theme Architecture:**
- Functional components: Use `useTheme()` hook for reactive theme access
- Class components: Use `withTheme()` HOC for theme injection
- Transform functions: Access `theme` from chartProps parameter
- Test infrastructure: Use `Theme.fromConfig()` for isolated testing
- Singleton pattern: `DEFAULT_THEME` for efficient fallbacks
**Test Architecture Cleanup:**
- Removed unnecessary theme setup from 30+ test files
- Eliminated legacy `dynamicTheme` cruft from logic tests
- Simplified theme assertions to focus on behavior vs implementation details
- Maintained theme testing only where legitimately needed
**Core Infrastructure:**
- ThemeController uses dynamic theme creation instead of static imports
- ChartProps uses singleton DEFAULT_THEME for efficient fallbacks
- Theme providers only at app root and isolated contexts (tests, storybook)
## Why This Was Needed
The previous architecture had static theme imports that:
- Always returned light theme values regardless of current theme mode
- Broke dark mode compatibility in visualizations (fixed in previous commit)
- Created performance overhead with redundant theme instance creation
- Prevented real-time theme switching across components
- Led to inconsistent theme access patterns
## Benefits
- ✅ Perfect dark mode support - no static dependencies to break theming
- ✅ True dynamic theming - all components react to theme changes
- ✅ Clean architecture - minimal providers, consistent patterns
- ✅ Better performance - singleton pattern eliminates waste
- ✅ Future-proof - ready for theme customization and user preferences
- ✅ Developer experience - clear patterns for every context
This transformation enables the next generation of Superset theming with
complete dynamic theme support and perfect dark mode compatibility.
