// E2E test for: notification sounds use Web Audio so they
// reliably play on iPad Safari after a single user gesture. Verifies
// (1) the AudioContext reaches `running` state after the user clicks
// the per-sound preview button in notification settings, (2) the play
// counter increments, and (3) the testPlay path is not subject to the
// 3-second burst-coalescing throttle.
