GLSL sample comments now say ±0.05 / ±0.075 matching the code and
spec table. Implementation notes gradient radius updated from 6-8
to 3-4 tiles.

Sync fog-shader-spec.md with actual shader values after #563 tuning:
light fog 0.25-0.35 (was 0.26-0.34), deep fog 0.55-0.70 (was 0.54-0.70).
Pseudocode now uses symmetric noise remapping (noise*2-1)*amp to match
the shader. Added first-call guard comment on _tint_bytes in fog_state.gd.

Ticket #563. Light fog alpha tuned to 0.25-0.35 range (was 0.25-0.55),
deep fog alpha set to 0.55-0.70 with zone temperature tint from
zone_tint_tex (bar=warm #2a1f15, hub=cool #1a1f2e, corridor=neutral
#1a1a1a). Two Perlin noise cycles: 8-10s light, 15-20s deep.
Zone tint texture now populated per-tile from server zone_id in
fog_state.gd with preservation across texture resizes.
