Players beside the board with avatar, online status, store count and
clock, the turn between them, a game-over card over the board, and a
move list with the newest move first and tags for extra turns,
captures and store gains. On phones the bottom player is shown below
the board.
Both clocks sit next to the players' names and count down in server time; the running one is highlighted and turns red under 30 seconds. They replace the offline countdown, so core drops TURN_TIMEOUT_MS, INACTIVE_TIMEOUT_MS, offlineSince and its text. Long info texts wrap on phones.
- Move list under the board with player, pit and what happened (extra
turn, capture, stones to the store, game over); collapsed on phones
- Selecting a move or using the arrow keys shows that position with a
banner and Back to live; pits are locked meanwhile and the banner says
when it is your turn
- Countdown while the opponent is offline on their turn
- on_game_end is handled, so games that end by timeout or inactivity end
on the page with the reason
