Add visual theme system for provider presets with custom icons and brand colors:
- Add PresetTheme interface supporting icon type and custom colors
- Claude Official: Claude brand icon + orange theme (#D97757)
- Codex Official: Codex brand icon + dark gray theme (#1F2937)
- Other presets: Default to theme blue (bg-blue-500)
- Custom config: Uses theme blue for consistency
Technical changes:
- Extend ProviderPreset and CodexProviderPreset interfaces with optional theme field
- Update ProviderPresetSelector to render icons and apply theme colors
- Support both Tailwind classes and hex colors via inline styles
- Remove unused Link import from ProviderCard
This restores the unique visual identity for official providers while
maintaining a unified theme color for third-party presets.
- Remove flex gap-3 from parent container to enable width animation
- Add conditional width (w-8/w-0) and margin-right (mr-3/mr-0) to drag handle button
- Add overflow-hidden to prevent icon overflow during width transition
- Content now smoothly shifts right by 44px when entering edit mode
- Maintains 200ms transition-all for smooth push animation
This creates a more natural "push-out" effect where the drag handle
appears to push the provider content aside, rather than just fading in.
- Add edit mode button next to settings in header
- Edit button turns blue when active
- Drag handles fade in/out with edit mode toggle
- Add smooth 200ms transition animation
- Add i18n support for edit mode (en/zh)
- Maintain consistent spacing between header elements
- Convert edit and usage buttons to icon-only ghost variant for cleaner appearance
- Reduce action button padding (px-2) and group spacing (gap-0) for more compact layout
- Add red hover effect to delete icon for better visual feedback
- Vertically center action buttons with provider info on desktop view
- Simplify provider URL link by removing icon and using soft blue color (blue-400/300)
- Reduce enable button width from 96px to 80px for better proportions
Restore the vibrant color palette from the pre-refactoring version while
maintaining shadcn/ui component architecture and modern design patterns.
## Color Scheme Restoration
### Button Component
- **default variant**: Blue primary (`bg-blue-500`) - matches old `primary`
- **destructive variant**: Red (`bg-red-500`) - matches old `danger`
- **secondary variant**: Gray text (`text-gray-500`) - matches old `secondary`
- **ghost variant**: Transparent hover (`hover:bg-gray-100`) - matches old `ghost`
- **mcp variant**: Emerald green (`bg-emerald-500`) - matches old `mcp`
- Updated border-radius to `rounded-lg` for consistency
### CSS Variables
- Set `--primary` to blue (`hsl(217 91% 60%)` ≈ `bg-blue-500`)
- Added complete shadcn/ui theme variables for light/dark modes
- Maintained semantic color tokens for maintainability
### Component-Specific Colors
- **"Currently Using" badge**: Green (`bg-green-500/10 text-green-500`)
- **Delete button hover**: Red (`hover:text-red-500 hover:bg-red-100`)
- **MCP button**: Emerald green with minimum width (`min-w-[80px]`)
- **Links/URLs**: Blue (`text-blue-500`)
## Benefits
- ✅ Restored original vibrant UI (blue, green, red accents)
- ✅ Maintained shadcn/ui component system (accessibility, animations)
- ✅ Easy global theming via CSS variables
- ✅ Consistent design language across all components
- ✅ Code formatted with Prettier (shadcn/ui standards)
## Files Changed
- `src/index.css`: Added shadcn/ui theme variables with blue primary
- `src/components/ui/button.tsx`: Restored all original button color variants
- `src/components/providers/ProviderCard.tsx`: Green badge for current provider
- `src/components/providers/ProviderActions.tsx`: Red hover for delete button
- `src/components/mcp/McpPanel.tsx`: Use `mcp` variant for consistency
- `src/App.tsx`: MCP button with emerald color and wider width
The UI now matches the original colorful design while leveraging modern
shadcn/ui components for better maintainability and user experience.
