/**
 * Activity / auto-hide mixin — wrapper layer over the free functions in
 * `activity.ts`.
 *
 * `activity.ts` owns the pure state-machine logic (bumpActivity, maybeHide,
 * dismissOverlay, setActivity). This mixin binds those functions to the
 * plugin's `_activityState`, `player`, `opts.inactivityMs`, and the
 * lifecycle-managed `timeout` — concerns that belong on the plugin, not on
 * the stateless free functions.
 *
 * Owns: bumpActivity, maybeHide, dismissOverlay.
