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.
