- Refactored 'event_session', 'event_presentation', 'event_file', 'event_location', and 'event_presenter' libraries to follow a Stale-While-Revalidate pattern.
- Implemented non-blocking background refreshes to allow instant UI rendering from IndexedDB cache.
- Parallelized nested collection loads (files, presentations) during background tasks to eliminate UI stalls.
- Standardized ID lookups using specific indices (event_location_id, event_id) for reliable local data retrieval.
- Resolved regression where aggressive ID overwriting caused relationship inconsistencies in background loads.
- Fixed reactive access to live queries in 'session_view.svelte' using proper Svelte 5 prefixing.
