- launcher/+layout.svelte: dead {:else if $events_slct.event_session_id} branch
(condition identical to preceding {#if}) replaced with correct
{:else if $events_slct.event_location_id} — shows "Select a session"
prompt when a room is chosen but no session is yet selected.
- launcher/[event_location_id]/+page.svelte: removed unreachable
handle_get_device_info() function (never called; pre-relay pattern
superseded by launcher_background_sync.svelte's run_device_heartbeat()).
Cleaned up now-unused imports.
