Centralizing Product Logic into a Shared Core

The same content was subject to subtly different visibility criteria depending on the entry point — whether encountered through search, recommendation, or the mini player. Each screen was independently evaluating its own display conditions, a structural pattern that does not surface in feature checklists but consistently undermines product coherence.

This update extracts content visibility rules from individual screens into a shared core. Decisions about what to show, in what order, and under what conditions are now owned by that core; each screen receives the output and handles rendering only. The same consolidation was applied to playback. State decisions previously distributed across the lock screen remote control, mini player, and reels playback have been unified, so audio session management, track loading, effects, and reverb all derive from a single flow.

The result is that control actions from the lock screen and from within the app reference the same playback state. The same content appears under consistent conditions across search and recommendation surfaces. Centralizing these decisions is the most direct path to a predictable and consistent listening experience.
