Preview scheduled every audio[data-start] regardless of data-hidden, so a hidden audio track was silent in the export but audible in preview — render was already correct, this was a preview-only parity bug. Web Audio scheduling now skips (and re-syncs on toggle) any audio clip under a data-hidden ancestor; the HTMLMedia per-tick volume path folds the same check into effectiveVolume without touching el.muted (transport-owned). Ships unflagged since it's a bugfix restoring parity. Also relabels the eye as Mute/Muted on audio-only track rows (icon, strikethrough label, undo-history copy), gated behind the new audio-track-mute canary — the relabel is a copy/UX change, kept separate from the behavior fix above.
