Styles were injected before hand/drag were instantiated, resulting in
zero-dimension tiles (CSS classes never added to page).

- match-live.js: always forward poll data to game (not only on move_count change)
  This was the root cause — resign/draw don't increment move_count, so the
  game never processed the status change or game_state update
- game.php: all match operations now use supabaseService() to bypass RLS
  (handleGameMove, handleResign, handleComplete all failed silently with user token)
- Add dedicated 'draw' action in game.php that atomically marks match completed
- Draw acceptance now calls action:'draw' instead of writing game_state only
- handleResign validates match isn't already completed (prevents double-resign)

Achievements:
- New scene with category filters, progress bars, tier badges

from their profile tab and apply for organizations with document proof.
Also fixes avatar.php to use SERVICE_KEY for storage uploads.

- Eliminate double polling: removed game.js own poller, use match-session's
  single 2s poll via handleLivePollData callback (halves network requests)
- Send last_move (from/to/san/promotion) in game_state so opponent gets
  exact move data — fixes castling, en passant, promotion animations
- Opponent moves now animate (piece slides) instead of board snap
- Capture particles now fire on opponent's captures too
- Castling sound+haptic plays for opponent's castles
- Draw flow: sender sees "sent" confirmation, receiver sees accept/deny
  dialog (30s timeout), both sides see result via game_state merge
- Emote dedup: timestamp tracking prevents repeated display on same emote
- Emotes use correct emoji lookup (getEmojiForKey) instead of 3 hardcoded
- Polling runs even during player's turn (emotes + draws must arrive anytime)
- Game end detection covers draw result ('draw' + 'aborted')
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- Draw offer now syncs: sender sees confirmation, receiver sees
  accept/deny dialog with 30s timeout
- Emotes now show the correct emoji (was hardcoded to 3 mappings,
  now uses actual emote key lookup)
- Emote dedup via timestamp tracking — no repeated display
- game_state is now MERGED server-side instead of overwritten,
  so emotes don't wipe draw offers and vice versa
- Polling runs regardless of whose turn it is (emotes/draws
  need to arrive during your own turn too)
- Draw accept/decline response properly detected by offerer

- Fix: clicking friends tab now always shows friends scene (not
  notifications). Tab click resets to root when already active.
- Friends list: sorted online-first, shows count, retry on error
- Pending requests: fetches requester profiles (name, avatar, level)
  instead of showing raw UUIDs
- Search: searches both username and display_name, debounced input
- Online tab: auto-refreshes every 15s
- Activity feed: timeAgo formatting, action icons
- API: added 'profiles' action for batch profile lookups, search
  now matches display_name too

The matches table requires these NOT NULL columns. Set match_type
to 'tournament' and parse time_control string for clock values.

PostgREST auto-decodes JSONB columns, so json_decode() fails when
the value is already an array. Added is_array() checks before decoding.

Ad area now flex:1 (absorbs all dead space above the board).
Hidden by default — only shown when an active campaign is loaded.
Game UI pushed further down for thumb reach.

- Add ad banner slot in the dead space above the board
- Move emote toggle button inline with player profile data
- Emote panel now opens below player bar (no more fixed overlay)
- Reduce top spacer to flex:0.4 so game sits near-center (slightly bottom-biased)
- Add api/ads.php endpoint to serve active campaigns from ad_campaigns table
- Ad system tracks impressions and filters by slot/game targeting
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Uses a flex:1 spacer div at the top of the layout instead of
manipulating board container flex. On tall screens, dead space
goes above the opponent bar — everything else stays packed at
the bottom within thumb reach.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

The justify-content:flex-end approach left dead space at top.
Instead: keep flex:1 on board container (fills screen), use
align-items:flex-end so the canvas sits at the bottom of its
container. Emote button stays at fixed position off the board.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Portrait mobile games should have everything within thumb reach at the
bottom. Removed flex:1 stretching and added justify-content:flex-end
so the board, bars, and controls all stack from the bottom up.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Board content now aligns to bottom (thumb zone) instead of center.
Emote button repositioned to fixed bottom-right, off the chess squares.
Control buttons enlarged to 48px+ with safe-area padding.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- Login: show brand logo via assetImg() instead of plain text, larger register link
- Bot select: 44px back button, difficulty color bars, fallback initials when portrait fails
- Chess board: raise max-width 400→500px, reduce padding — fills more screen
- Chess controls: min-height 44px, better contrast (#e2e8f0), larger border-radius
- Ludo board: raise cap 360→420px to fill available space
- Ludo exit button: 44px circular touch target instead of rectangular
- Tab bar items: min 44px touch targets with centered content
- HUD bell button: 36→44px
- Game menu: staggered entrance animation on buttons/chips
- Fix 9px font in ludo panels → 10px minimum

Ludo multiplayer:
- Sync state to server on EVERY turn change (including no-valid-moves pass)
- Use turn_count to detect stale vs fresh server state (prevents re-processing)
- Non-host players poll at 1.5s and receive dice rolls + board state
- Bot turns run only on host, results synced to server for other players
- Fix double-encoding of game_state/positions in API
- Play notification sound when turn returns to player

Chess multiplayer:
- Detect move type (check/capture/castle) from FEN diff on received moves
- Show check highlight (red king square) for opponent's checking moves
- Play correct SFX (check/capture/castle) instead of generic 'move'
- Show last-move highlight squares for received moves
- Skip polling during recovery to prevent SFX burst on reconnect
- Track captured pieces from opponent's moves
- Sync move list from server history
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Three critical multiplayer sync issues fixed:

1. Resign now notifies server (action:'resign') BEFORE ending locally.
   Opponent's polling detects status:'completed' + result and shows win.

2. Reconnect recovery completely rewritten:
   - Determines player color from match data (white_player_id vs userId)
   - Flips board correctly for black
   - Sets lastKnownMoveCount from server to prevent duplicate move processing
   - Detects if game already ended while disconnected (opponent resigned)
   - Restores canSelect with correct color check

3. sendLiveMove now includes clock times (white_time_remaining_ms,
   black_time_remaining_ms) so opponent sees accurate clocks.

Panel positions:
- Forced direction:ltr on panel rows so Green=top-left, Yellow=top-right,
  Red=bottom-left, Blue=bottom-right — matching the board zones visually.
  (The page is RTL Arabic which was reversing element order.)

Exit button:
- Added exit button (✕) next to dice area
- Single player: confirms then ends game as loss
- Multiplayer: notifies server to replace player with bot, then exits
- Confirmation dialog prevents accidental exits
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Problem 1: Reconnection reset board to starting position
- engine.create() always starts fresh
- FIX: if params.recovered, fetch match from server → engine.load(current_fen)
- Also restores clock times + determines whose turn from FEN

Problem 2: Opponent name stuck on 'جاري التحميل'
- params.opponentId was undefined (not passed on reconnect or matchmaking)
- FIX: if no opponentId in params, fetch match → get white/black_player_id → find opponent
- Uses fetchAndRenderOpponent() helper to update avatar/name/level

Problem 3: Other player can't see moves after reconnect
- This was because board reset to start position
- Now board loads current_fen from server → correct position displayed
- Polling continues from correct move_count
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Emotes now pop up next to the player panel that sent them and gently
float up in place before fading. Duration increased from 1.8s to 3s.
Multiplayer sync unchanged — still uses sendEmote/onEmoteReceived.
Bot emotes in ludo also use the new positioned animation.

Ludo:
- Each panel shows: avatar (photo/bot🤖), name, level
- YOUR panel shows your profile photo + display_name + level
- Bot panels show 🤖 emoji with colored border matching their zone
- Panel positions already match zone colors (Green TL, Yellow TR, Red BL, Blue BR)

Chess:
- Opponent bar: photo (bot portrait for bots, profile pic for humans) + name + level
- YOUR bar: your profile photo + display_name + Lv.X
- Gold border around your avatar, blue border around opponent's
- Live mode: fetches opponent profile → updates avatar, name, level dynamically
- Bot mode: shows Stockfish portrait + bot name + 'بوت' label

Both games now feel player-centric — you always see WHO you're playing against
with their real identity, not generic 'Opponent' or 'Bot 1' text.

Chess game scene:
- Imports and calls matchLive.start(matchId, 'chess', callbacks)
- Creates localStorage entry → browser refresh auto-resumes
- matchLive.session.destroy() on endGame → clears recovery

Ludo game scene:
- Same pattern: matchLive.start(matchId, 'ludo', callbacks)
- Clears session on endGame

Now the flow works:
1. Player enters live game → matchLive.start() saves to localStorage
2. Player refreshes browser → engine boot finds recovery → verifies server → auto-rejoins
3. Game ends normally → matchLive.session.destroy() clears localStorage
4. Player goes to homepage after game → no recovery popup (correct)
