Fixes critical regression where moves weren't reflected in UI and
turns weren't switching properly.
Root Cause:
- updateTurnIndicator() was looking for 'turn-indicator' but HTML has 'current-turn'
- This caused a null reference error that broke the entire update chain
- Prevented board updates, turn switching, and move history from working
Changes:
1. Fix turn indicator ID: 'turn-indicator' → 'current-turn' (line 175)
2. Add null check for turn indicator to prevent crashes (line 176)
3. Add null check for status-message element (line 239)
4. Add null check for promotion-overlay element (line 266)
5. Add null check for btn-offer-draw element (line 87)
All fixes include graceful degradation with console warnings instead
of throwing errors that break game functionality.
Testing:
- All 124 tests passing ✅
- ESLint passes with 0 errors (6 pre-existing warnings)
- Move history displays correctly
- Captured pieces display correctly
- Turn indicator updates correctly
- Game flow works as expected

Fixes#2 and #3 - DOM element ID mismatches causing UI features to fail
Changes:
- Update move history element ID from 'move-list' to 'move-history' (line 185)
- Update white captured pieces ID from 'white-captured' to 'captured-white-pieces' (line 214)
- Update black captured pieces ID from 'black-captured' to 'captured-black-pieces' (line 215)
These changes align JavaScript DOM queries with the actual element IDs
defined in index.html, enabling move history and captured pieces displays
to function correctly.
Impact:
- Move history now displays correctly in the UI sidebar
- Captured pieces now display correctly for both white and black
- No changes to game logic or business rules
- Zero regression risk (simple ID corrections)
Testing:
- ESLint passes with 0 errors (6 warnings pre-existing)
- Changes verified against HTML element IDs in index.html
