Three new single-keyframe WOL presets complement the
existing 4-keyframe day/night cycle from --gen-light:
• --gen-light-cave — dim cool ambient (0.05, 0.05, 0.07)
+ heavy short-range fog (15..80)
for cave / mine interiors
• --gen-light-dungeon — warm torchlit ambient (0.18, 0.14,
0.10) + medium fog (25..200) for
dungeon / crypt interiors
• --gen-light-night — cold blue ambient (0.06, 0.07, 0.12)
+ moonlit directional + far fog
(80..500) for always-night zones
Each preset emits a single-keyframe WOL since enclosed /
fixed-time scenes don't vary with time-of-day. All three
share an emitLightPreset helper so adding more presets
(e.g. --gen-light-tundra, --gen-light-volcanic) is one
line of registration + a maker function.
All four WOL outputs validate clean under --validate-wol
(1 or 4 keyframe(s) valid).
