This commit addresses three critical bugs reported after initial PR:
1. **Promotion dialog not closing after piece selection**
- Changed from `style.display` to HTML5 `.showModal()` and `.close()`
- Fixed selector from `.promotion-piece .symbol` to `.promotion-piece .piece-icon`
- Fixed data attribute from `dataset.type` to `dataset.piece`
- Dialog now properly closes after user selects promotion piece
2. **Pawn showing as queen before user selection**
- Removed automatic promotion to queen in GameController.js:112-115
- Now emits 'promotion' event WITHOUT pre-promoting
- User sees pawn until they select the promotion piece
- Promotion happens only after user makes their choice
3. **Column resizing not fully fixed**
- Added explicit `max-width: 250px` to `.game-sidebar` and `.captured-pieces`
- Added explicit `max-width: 250px` to `.move-history-section`
- Added `overflow: hidden` to `.captured-list` and `overflow-x: hidden` to `.move-history`
- Added `min-width: 600px` to `.board-section`
- Added `width: 100%` to all sidebar components for proper constraint application
- Columns now maintain stable widths even with content changes
**Files Changed:**
- `js/main.js` - Fixed promotion dialog handling
- `js/controllers/GameController.js` - Removed auto-promotion
- `css/main.css` - Added width constraints and overflow handling
**Root Causes:**
- Dialog: Mixing HTML5 dialog API with legacy display styles
- Promotion: Auto-promoting before showing user dialog
- Resizing: Missing explicit max-widths allowed flex items to grow with content

This commit fixes two bugs:
1. Issue #7: Missing status message DOM element
- Added #status-message div to index.html
- Added CSS styling with type-based classes (info, success, error)
- Enhanced showMessage() to apply type classes for visual styling
- Messages auto-hide after 3 seconds with fade-in animation
2. Column resizing visual bug:
- Changed grid-template-columns from flexible (1fr 3fr 1fr)
- To fixed minimum widths: minmax(200px, 250px) minmax(600px, 3fr) minmax(200px, 250px)
- Prevents columns from resizing when content changes (captured pieces, move history)
- Maintains stable layout throughout gameplay
Tests:
- Added status-message.test.js with 10 test cases
- Added column-resize.test.js with 8 test cases
- Tests verify DOM element existence, CSS styling, auto-hide behavior, and layout stability

Fixes inverted display of captured pieces in UI sidebars.
Issue:
- "Captured by White" was showing white pieces
- "Captured by Black" was showing black pieces
This is backwards! The display should show:
- "Captured by White" = black pieces that white captured
- "Captured by Black" = white pieces that black captured
Root Cause:
The capturedPieces object stores pieces by their color:
- capturedPieces.white = white pieces that were captured (by black)
- capturedPieces.black = black pieces that were captured (by white)
So the display logic was inverted.
The Fix:
- whiteCaptured (header "Captured by Black") now displays captured.white
- blackCaptured (header "Captured by White") now displays captured.black

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
