Reduces unnecessary re-renders of the PlayerList component by memoizing PlayerCard. The player list is derived from the global game state on every render, causing object references to change even when data is identical. This change: 1. Wraps PlayerCard in React.memo with a custom comparison function. 2. Checks only relevant fields (id, nickname, status, etc.) for equality. 3. Explicitly ignores the unstable `onKick` callback since its behavior is stable. This significantly reduces rendering work during frequent state updates (e.g. timers).

⚡ Performance Improvement
Optimized the
PlayerCardcomponent inPlayerList.tsxto prevent unnecessary re-renders.Why:
The
GameRoomcomponent regenerates theplayersarray viaObject.values(activeState.players)on every render (triggered by timers, chat, or other player actions). This caused allPlayerCardcomponents to re-render even if their data hadn't changed.What:
PlayerCardinReact.memo.arePlayerCardPropsEqualfunction to compare relevant player fields (id,nickname,role,is_alive, etc.).onKickprop from comparison because it's passed as a new inline function/closure on every render, but its underlying behavior (setKickTarget) is stable.Impact:
