Presence avatars

useSelf / useOthers / useLeavers split the roster. Leavers stay visible for two minutes after member_left, then drop.

const { store } = useChat({ roomId: "lobby" });
const self = useSelf(store, userId);
const others = useOthers(store, userId);
const leavers = useLeavers(store);
const avatars = usePresenceAvatars(store, userId);

UI location (which slide or field) lives on presence_patch.uiLocation. useLocations() follows that. GPS stays on location_update / useLocation.

room.presence.enter(data) / update(data) send that patch. Joining the occupancy set is attach(), not a second enter call.

usePresenceListener() refreshes presence.get() on enter/leave patches. presence.leave() hides you from presenceMembers and keeps the socket open.
