// on an interaction-decay timer — the popup pill showed ~10s after the
// tap while recording itself started in 0.2s (verified 2026-09-17 via
// StackScroll timestamps). One short 60ms tick makes the notification
// unambiguously alerting: the pill pops with the tap. Sound stays off;
// a beep at record start would be worse than the tick.
// Note: createNotificationChannel over an existing id refreshes
// vibration/sound (app-controlled), only importance stays user-locked.
