Walk every speaking beat at export time, reuse current scene's beatAudioMap, and synth the rest via BYO TTS or /api/beat-audio with concurrency 4. Show a progress toast on the play page while collecting. Gallery export keeps audio in a sidecar localStorage key so the first paint is not blocked by JSON.parse-ing several MB of base64; the gallery lazy-loads it after the first scene image, then plays per-beat audio with a mute toggle persisted to localStorage. .infiplot share files embed audioByBeatId in the doc itself (v2); on import the data URIs survive scene swaps and feed back into the per-beat audio map so replayers hear the original voices for free.
