Parley Hatch acc8137f4a fix(pipeline): kill dither speckle + atlas geometry lies (post-playtest)
Parley's review: dither full of green spots, baked rooms don't match the
nav graph (doors painted on closed walls, real openings off-center).
Both root-caused:

- pixelate.py: the nearest-color LUT was spaced in LINEAR RGB, cramming
  the whole shadow range into ~4 cells — dark picks were effectively
  arbitrary (green/teal confetti in warm near-blacks). LUT is now
  sRGB-spaced, diffusion error is gamut-clamped (no more blue blobs at
  torch highlights), and a new --overshoot penalty forbids choosing a
  color more saturated than the source. Green-dominant dark pixels on
  the test frame: 5.2% -> 0.02%, while palette usage went UP (107 -> 135
  colors). Recipe rev 2: append --overshoot 6.

- fpv.js: new directedVantage(env, region, dir) — per-(room,facing)
  camera instead of one room-wide vantage. Open ahead: stand in a cell
  whose straight-ahead ray escapes through the actual gap (the passage
  you walk is centered, 2-7 cells deep). Closed ahead: stand ~2 cells
  from the wall, deliberately OFF the room's axis — a symmetric stage
  begs the model to paint a centered focal door; an off-axis dead-end
  corner doesn't. Walls also render under their own fixed seed and an
  emphatic sealed-masonry prompt clause (cfg 1.0 negatives are inert).

Validated on seed 7 room 1: the closed-N phantom door is gone; the open-S
passage is dead-center. Full campaign re-bake follows as its own commit.

Also: rest-overlay no longer sticks without a keyup, in-combat drink
message, feathered sprite mask, no monster packs on floor 1.
