Story after Oliver's first test: metal, a straight prologue, 2x3 chapters

- The gore bed is "Dystopian Survival", made loopable: the last ten
  seconds cross-faded into the first ten, 203.5 s, as MP3 at 128k (the
  decoder strips the encoder's delay, so the seam has no gap). High-pass
  at 40 Hz instead of 800, level matched to the menu theme.
- The prologue no longer drops into gore for a moment: after the turn,
  act I's card and cup take over directly.
- RESET STORY under the build stamp (two taps; test only). It resets
  the story, league, cups and title, keeps the level, and pushes at once
  so the mirror cannot hand the old act back.
- The story screens have sound: a whoosh and a boom for the act card,
  applause and the rack's own click as each weapon lands, applause and
  a pock per arcade door on the act's end.
- Chapters are six games: mid-boss after three, the horde after four,
  the act boss after six.

v384, staging only.
