Unifying Playback State Across UI Surfaces
Reworked the playback control flow so that the lock screen, mini player, and main player all reference the same audio state.
A single audio stream is referenced simultaneously by multiple UI surfaces: the lock screen remote control, the mini player, the reels transition layer, and the main player view. When these surfaces fall out of sync, audio continues playing after an apparent stop, or display information updates while the underlying state does not. These inconsistencies do not surface in a feature checklist, but they directly degrade the reliability of the playback experience.
The objective was to ensure all control surfaces reference a single, consistent playback state. The audio pipeline was revised across session and track load timing, effect and reverb application points, and fade handling during transitions. Track transitions now proceed without interruption.
On the UI side, a drawer menu was added and body typography was refined. Mode transition paths and session handling were consolidated so the interface operates as a coherent flow rather than a collection of discrete features. Consistent alignment between audio state and UI state is the foundation of a trustworthy playback experience.
