Fixed critical issue where sidebars were completely collapsed/hidden in landscape mode, showing only 33px accordion headers instead of full content. ROOT CAUSE: - Sidebar accordions (<details> elements) were collapsed by default - Native <details> browser behavior prevented CSS-only expansion - Sidebar content was present but hidden behind collapsed accordion SOLUTION: 1. JavaScript: Added handleLandscapeAccordions() to auto-open sidebar accordions when in landscape orientation (≤915px width) - Runs on DOMContentLoaded, orientationchange, and resize events - Uses matchMedia to detect landscape mode - Sets 'open' attribute on all .sidebar-accordion elements 2. CSS: Enhanced sidebar container styles in landscape mode - Set overflow: visible on sidebars (was hidden) - Set height: auto on sidebars and .actual-content wrappers - Forced accordion content visibility with !important rules - Made summary non-clickable in landscape (pointer-events: none) 3. Tests: Updated landscape test to validate sidebar visibility - Now checks sidebar visible/hidden state - Validates sidebar height (should be >100px, not 33px) - Added debug tests for troubleshooting RESULTS: - Sidebar height: 1387px (Android) / 1536px (iPhone) ✓ - Accordion state: OPEN ✓ - All sidebar content fully visible ✓ - No horizontal scroll ✓ Test files: - tests/mjs/54-landscape-mode-test.mjs (updated with sidebar checks) - tests/mjs/60-sidebar-content-debug.mjs (new debug test) - tests/mjs/61-sidebar-positioning-debug.mjs (positioning debug) - tests/mjs/62-sidebar-computed-height-debug.mjs (height debug) - tests/mjs/63-media-query-match-test.mjs (media query validation)
