Fix inconsistent modal overlays by migrating all custom implementations
to the unified shadcn/ui Dialog component with proper z-index layering.
Changes:
- Update Dialog component to support three z-index levels:
- base (z-40): First-level dialogs
- nested (z-50): Nested dialogs
- alert (z-[60]): Alert/confirmation dialogs (using Tailwind arbitrary value)
- Refactor all custom modal implementations to use Dialog:
- EndpointSpeedTest: API endpoint speed testing panel
- ClaudeConfigEditor: Claude common config editor
- CodexQuickWizardModal: Codex quick setup wizard
- CodexCommonConfigModal: Codex common config editor
- SettingsDialog: Restart confirmation prompt
- Remove custom backdrop implementations and manual z-index
- Leverage Radix UI Portal for automatic DOM order management
- Ensure consistent overlay behavior and keyboard interactions
This eliminates the "background residue" issue where overlays from
different layers would conflict, providing a unified and professional
user experience across all modal interactions.
Convert all MCP-related modal windows to use the unified shadcn/ui Dialog
component for consistency with the rest of the application.
Changes:
- McpPanel: Replace custom modal with Dialog component
- Update props from onClose to open/onOpenChange pattern
- Use DialogContent, DialogHeader, DialogTitle components
- Remove custom backdrop and close button (handled by Dialog)
- McpFormModal: Migrate form modal to Dialog
- Wrap entire form in Dialog component structure
- Use DialogFooter for action buttons
- Apply variant="mcp" to maintain green button styling
- Remove unused X icon import
- McpWizardModal: Convert wizard to Dialog
- Replace custom modal structure with Dialog components
- Use Button component with variant="mcp" for consistency
- Remove unused isLinux and X icon imports
- App.tsx: Update McpPanel usage
- Remove conditional rendering wrapper
- Pass open and onOpenChange props directly
- dialog.tsx: Fix dialog overlay and content styling
- Change overlay from bg-background/80 to bg-black/50 for consistency
- Change content from bg-background to explicit bg-white dark:bg-gray-900
- Ensures opaque backgrounds matching MCP panel style
Benefits:
- Unified dialog behavior across the application
- Consistent styling and animations
- Better accessibility with Radix UI primitives
- Reduced code duplication
- Maintains MCP-specific green color scheme
All dialogs now share the same base styling while preserving their unique
content and functionality.
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.
