Subject: [PATCH] feat: create reusable CSS components (Phase 3)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Created static/css/components/feed-cards.css (280 lines):
  * Comprehensive styles for feed/news cards
  * Classes: .feed-header, .feed-stream, .feed-card, .feed-hd, .feed-ava
  * Includes variants: compact, borderless, highlighted
  * Responsive design with mobile breakpoints
  * Replaces duplicated styles found in 6+ templates

- Created static/css/components/ios-search.css (160 lines):
  * iOS-style search component
  * Classes: .ios-search, .ios-search-input, .ios-search-clear
  * Size variants: sm, lg
  * Auto-showing clear button
  * Replaces duplicated styles found in 4+ templates

- Updated static/css/components/index.css:
  * Added imports for feed-cards.css and ios-search.css
  * Added import for variables.css
  * Provides single entry point for all CSS components

Benefits:
- Eliminates ~150 lines of duplicated CSS across templates
- Centralized styling for consistent UI
- Easy to maintain and update
- Uses CSS custom properties from variables.css
- Ready for use in new features

Next: Replace inline styles in templates with component imports

Tests: All 12 static file tests passing ✅
