+body:
+
+Twungeon's party and turn rules have been tightened around a predictable
+four-player multiplayer loop. Each character now occupies one of four fixed
+slots with a stable color: blue, green, red, or yellow. A fifth spawn is
+rejected as party-full, and defeated characters continue to hold their slot
+until the floor concludes.
+
+Completing a floor now clears the active party and returns the game to its
+dormant state with the next dungeon ready. Connected and authenticated viewers
+remain eligible to spawn again, so every floor begins with a fresh, first-come
+party formation instead of carrying character state forward.
+
+The player phase now runs on a rolling five-second deadline. The first accepted
+command from each active player restarts that deadline from the command's
+arrival time. Repeat commands, rejected actions, and duplicate submissions do
+not extend the phase, keeping turns responsive without allowing one player to
+stall the game indefinitely.
+
+The Twitch Extension now uses the same slot colors across dungeon markers,
+names, party status, action feedback, and administrative views. Its single
+frontend adapts to desktop and mobile contexts: mobile viewers receive larger
+movement and action controls plus an at-a-glance identity, color, health,
+action-point, and healing display.
+
+Documentation and acceptance coverage were updated alongside the mechanics.
+The completed change passed the domain and integration suites, linting, type
+checking, production build, and desktop and mobile browser layout checks.
+
+The implementation is recorded in
