- useMediaWebSocket: shallowRef mediaIndex/tasks/loading/error/connected
to eliminate Proxy overhead on the entire library data structure.
- useMediaWebSocket: replace per-task setTimeout leak with single 3s
sweep interval for completed task cleanup.
- App.vue: remove {deep:true} watcher on mediaIndex; shallow ref change
is sufficient to trigger search worker sync.
- useGamepadNavigation: rAF only when gamepads are connected; idle
fallback to 500ms setTimeout to stop permanent 60fps CPU drain.
- useKeyboardNavigation: deduplicate synced scroll rAF requests to
prevent overlapping animation frames.
- MediaDetail/SeriesFullView/CollageHero: pause, clear src, and load()
video elements on unmount and before ref replacement to release
decoder/memory resources.
- MediaDetail/SeriesFullView: clear all volume fade intervals on
unmount to stop interval timer leaks.
