juanatsap 0e33d7c886 docs: Phase 2 - Add Skeleton Loaders and Color Theme System sections
MAJOR FEATURES DOCUMENTED:

### Section 11: Skeleton Loaders (lines 1638-1764)
Component-level content placeholders for smooth loading transitions

KEY FEATURES:
- Pixel-perfect skeleton matching (header, photo, sections, experience)
- GPU-accelerated shimmer animation (1.8s ease-in-out infinite)
- Component-wrapper architecture (dual-state: actual + skeleton)
- HTMX event integration (beforeSwap → show, afterSettle → hide)
- Zero layout shift during transitions
- Accessibility: Respects prefers-reduced-motion
- Print-friendly: Skeletons hidden in @media print

IMPLEMENTATION:
- static/css/skeleton.css (341 lines)
- templates/partials/skeleton-loader.html
- HTMX event listeners in main.js
- tests/mjs/12-skeleton-language-transitions.test.mjs

BENEFITS:
- Professional UX like modern SPAs (LinkedIn, Facebook)
- Smooth 250ms fade transitions
- Reusable for any HTMX swap operation
- Independent component loading states

### Section 12: Color Theme System (lines 1767-1939)
Dynamic light/dark/auto theme switching with CSS custom properties

KEY FEATURES:
- Three theme modes: Auto (system), Light, Dark
- CSS custom properties for instant switching
- localStorage persistence across sessions
- System integration via prefers-color-scheme
- Dynamic button colors per theme mode:
  * Auto: Purple (#9b59b6)
  * Light: Orange/Yellow (#f39c12)
  * Dark: Blue (#3498db)
- Dual-theme architecture (Color + Layout independent)

IMPLEMENTATION:
- static/css/color-theme.css (258 lines)
- static/hyperscript/color-theme._hs (59 lines)
- setColorTheme(), initColorTheme() functions
- Fixed floating button with theme cycling
- tests/mjs/13-color-theme-switcher.test.mjs

BENEFITS:
- User comfort (choose preference or follow system)
- Instant switching (CSS custom properties, no reflow)
- Accessible (WCAG AA contrast compliance)
- Zero JavaScript for theme application
- Separation of concerns (color vs. layout)

DOCUMENTATION QUALITY:
- Complete before/after code examples
- Architecture pattern breakdowns
- Comprehensive benefits lists
- Testing information included
- Pixel-perfect matching tables (skeletons)
- CSS custom properties reference (theme)

IMPACT: +306 lines comprehensive documentation
TIME: ~90 minutes (partial Phase 2 complete)
REMAINING: HTMX patterns enhancement, hover sync documentation
