Version 0.9.1

Fixes

• Export length is entered as minutes and seconds — the single "m:ss" field read a bare number as seconds, so typing "15" for a 16-minute video slammed the speed into the 4× cap and rewrote the runtime unexplained. Separate min/sec boxes make the units explicit; when a target genuinely exceeds the 0.25–4× range, the readout now says so and names the nearest reachable length. The readout keeps a fixed two-line height (no more modal reflow), and the number inputs drop their spinner buttons.
• Interactive transcript exports explain a missing media file — a page moved away from its media now shows what to do (keep the pair together, or point the src at a hosted URL) instead of a dead player, and carries a "Made with Hyperaudio" footer linking back to the editor.
• Recents docs remember their media reference — the interactive-transcript dialog prepopulates from the loaded doc (older entries backfill from their filename-shaped name), and loading a doc no longer leaves the previous media's URL where the export could pick it up.

Known issue

• One report remains of the interactive-export dialog prepopulating empty from a Recents doc (#446) — under investigation.
