-# Queue Simplification
-
-**Status:** COMPLETED
-
-## Summary
-
-Simplified Queue from ~524 LOC to ~405 LOC. Removed convenience features only used in tests/docs, kept essentials for async media operations.
-
-## Why Queue Exists
-
-All writes are async requests. Queue handles:
-
-- Supersession (rapid clicks → only last executes)
-- AbortController propagation
-- Task lifecycle tracking (pending/success/error)
-- Error surfacing for UI
-
-## Removed
-
-- `cancel()`, `flush()`, `queued` getter
-- `TaskScheduler`, `QueueConfig`, `schedule` param
-- `delay()`, `microtask`, DOM schedulers (`raf()`, `idle()`)
-- `onDispatch`, `onSettled` hooks
-
-## Final API
-
-```ts
-interface Queue<Tasks> {
-  readonly tasks: TasksRecord<Tasks>;
-  readonly destroyed: boolean;
-  enqueue<K>(task: QueueTask<K>): Promise<Tasks[K]['output']>;
-  abort(name?: keyof Tasks): void;
-  reset(name?: keyof Tasks): void;
-  destroy(): void;
-  subscribe(callback: StateChange<TasksRecord<Tasks>>): () => void;
-}
-```
