Shell (match UI, player plates, dialogs, reactions, queue, VS, challenge):
flat Night Arcade surfaces, turn timers on the plates, banners for your
turn / time low / waiting, a claimable disconnect ring, and a cancel that
waits for an in-flight join so it never leaves a ghost queue row.
tests/play/shell.mjs: 144/147 (the 3 were the invite bugs below).

Domino: flat white tiles on a lip, a purple-tinted table, playable tiles
lifted, the hand fanned with translate. tests/play/domino.mjs: 785/785
against the bot, scripted positions and online.

friends.php: a ludo invite wrote a column ludo_matches does not have (400)
and opened a four-seat table; domino and ludo invites stored players as a
JSON string, so check-invites never showed them to the friend.
