93889ab9bd fix: correct API integration and complete missing features 
Fix API response format mismatches and implement all remaining features:

**API Integration Fixes:**
- Fix ManipulationPanel to use `colors` instead of `results` from API responses
- Fix gradient endpoint to use `gradient` array from API response
- Fix color blindness simulator to use correct field names (`input`/`output` vs `original`/`simulated`)
- Fix text color optimizer request field (`backgrounds` vs `background_colors`)
- Fix method name casing: `simulateColorBlindness` (capital B)
- Add palette generation endpoint integration

**Type Definition Updates:**
- Update GradientData to match API structure with `gradient` array
- Update ColorBlindnessData to use `colors` with `input`/`output`/`difference_percentage`
- Update TextColorData to use `colors` with `textcolor`/`wcag_aa`/`wcag_aaa` fields
- Add PaletteGenerateRequest and PaletteGenerateData types

**Completed Features:**
- Harmony Palettes: Now uses dedicated `/palettes/generate` API endpoint
  - Simplified from 80 lines of manual color theory to single API call
  - Supports 6 harmony types: monochromatic, analogous, complementary, split-complementary, triadic, tetradic
- Text Color Optimizer: Full implementation with WCAG compliance checking
  - Automatic black/white text color selection
  - Live preview with contrast ratios
  - AA/AAA compliance indicators
- Color Blindness Simulator: Fixed and working
  - Shows difference percentage for each simulation
  - Side-by-side comparison view
- Gradient Creator: Fixed to use correct API response structure
- Batch Operations: Fixed to extract output colors correctly

**UI Improvements:**
- Enable all accessibility tool cards (remove "Coming Soon" badges)
- Enable harmony palettes card
- Add safety check for gradient state to prevent undefined errors

All features now fully functional and properly integrated with Pastel API.

     - Tritanopia (blue-blind, rare)
   - Side-by-side comparison of original vs simulated
   - Support for multiple colors (up to 10)
   - Educational information about each type
   - Accessibility tips and best practices

   - Process up to 100 colors at once
   - Text input (line-separated or comma-separated)
   - 5 operations supported:
     - Lighten/Darken
     - Saturate/Desaturate
     - Rotate hue
   - Adjustable amount slider
   - Export processed colors
   - Live validation and color count

**API Query Hooks:**
- Add useSimulateColorBlindness hook
- Add useTextColor hook
- Export ColorBlindnessRequest and TextColorRequest types

**Files Added:**
- postcss.config.mjs
- .env.local
- ../pastel-api/.env
- app/accessibility/colorblind/page.tsx
- app/palettes/harmony/page.tsx

**Files Modified:**
- app/globals.css (Tailwind v4 migration)

- app/batch/page.tsx (functional implementation)
- lib/api/queries.ts (new hooks)
- package.json (dev scripts)
- tailwind.config.ts (simplified, CSS-first)

All features build successfully and are ready for testing.
Development server can now run with API via `pnpm dev:all`.

Implement full palette export system with multiple formats:

**Export Utilities (lib/utils/export.ts):**
- exportAsCSS() - CSS custom properties (:root variables)
- exportAsSCSS() - SCSS variables ($color-name format)
- exportAsTailwind() - Tailwind config module export
- exportAsJSON() - Structured JSON with color objects
- exportAsJavaScript() - JavaScript array of colors
- downloadAsFile() - Browser download helper
- ExportColor interface for typed exports

**ExportMenu Component:**
- Format selector dropdown (5 formats)
- Live preview of export code
- Syntax-highlighted code display
