Board Layout (matches reference image):
- Color order: Red(TL), Blue(TR), Yellow(BR), Green(BL)
- Fixed SHARED_PATH: 52 squares going clockwise correctly
- Fixed START_SQUARES: [0, 13, 26, 39] — NOW MATCHES rules.js
- Fixed HOME_COLUMNS: correct paths toward center per player
- Fixed SAFE_SQUARES: match official Ludo star positions
- Fixed HOME_ENTRY: correct squares before entering home column

Rules Engine fixes:
- START_POSITIONS now matches board-map START_SQUARES (was off by 1!)
- Capture logic: only checks pieces on shared path (pos < 52)
- Home column pieces CANNOT be captured (pos >= BOARD_SIZE check)
- Three consecutive 6s = piece goes back home, lose turn
- Exact finish requirement enforced (must land exactly on 58)
- Extra turn on: rolling 6, capturing, finishing
- Bot AI priority fixed: finish > capture > enter > advance furthest

Dead code removed:
- doMove() cleaned up (was return + unreachable code)

Color order fixed in game scene:
- COLORS array matches rules.js order
- COLORS_LIGHT matches too
