Subject: [PATCH] fix: resolve promotion dialog bugs and column resizing issues
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit addresses Issue #7 and fixes the column resizing bug:

1. Issue #7 Fix (already implemented):
   - Added status-message element to index.html
   - Added CSS styling for status messages
   - Messages now display visually to users

2. Column Resizing Bug Fix:
   - Changed grid-template-columns from flexible minmax() to fixed widths
   - Changed from: minmax(200px, 250px) minmax(600px, 3fr) minmax(200px, 250px)
   - Changed to: 250px 600px 250px
   - Fixed sidebar widths to 250px (removed width: 100%, max-width)
   - Fixed board section width to 600px (removed min-width, width: 100%)
   - Fixed move-history width to 218px (accounting for padding)
   - Added justify-content: center to game-container

Root cause: The minmax() function with fractional units (3fr) was causing
the browser to recalculate column widths when sidebar content changed
(captured pieces being added). Fixed widths prevent this reflow.
