// runStartSequence, gating the session's transition to "running" until it completes -
// this file exercises that for each of those four types, plus pause/resume/finish.
//
// Every effect/voice is silenced via raceAudio.events so the sequence's own audio
// playback (real <audio> elements, speechSynthesis) never has to actually complete in a
// headless browser with no sound hardware - only the sequence's own timers (countdown,
// light stepping, start delay) gate progress, which this file sets to near-zero except
// for one full-length run (the heat scenario) that keeps a real countdown to prove the
// countdown display itself updates.
