Fixes the two baked-plane defects from the oddity pass (follow-up ratatoskr-backdrop:follow_up:ridge-plane-rebake):

  • dark seam: the mid plane's spur showed through the near plane. Far planes' alpha is now brought to what the nearer layers leave open in the opaque frame (most_open, 48 px margin for the runtime slide).
  • transparent wedge at x>=1252 of the near plane: the near layer keeps its body opaque down to the horizon.
  • export.check_near_cover, run at write_bake on every frame: refuses a near plane with a transparent column or a hole between crest and horizon.

Vienna rebaked only (b464e375319f -> 12e733dc9f09, same cached mosaic, 1.5 MB of planes). Default scene not flipped; no TypeScript touched.

Soul pass: seam gone in all frames; wedge gone above the horizon; check refuses the old wedge, edge strips and holes. Known residual: below the horizon, x 1252-1280, the near body still dissolves early (a narrow dip in the haze band, rows ~320-380); the check stops at the horizon row. Full python suite not run (no Copernicus tiles here); nine relevant tests ran against the cached mosaic and passed.

Fixes the mid-plane spur showing through the near plane and the transparent
edge wedge at x>=1252. export.check_near_cover refuses a near plane with a
transparent column or a hole between crest and horizon, at write_bake.
