- Default seats for 2 players: [0, 2] (BL vs TR) instead of [0, 1] (adjacent)
- Panel layout: opponent at top-right for 2-player (diagonally opposite)
- Corner glow uses boardSlot instead of player index
- Dim inactive home zones, home columns, center triangles, start squares
- Matches the getSeatPositions() in room.js which already returned [0, 2]
