- WEATHER_DENSITY bumped: sunny 0.20->0.55, cloudy 0.70->0.85,
night 0.45->0.65. Stormy stays at 1.0 (already maxed).
Even 'sunny' now has visible cloud structure, not just clear sky.
- clouds3d: add a second fBm layer at 4x frequency for fine detail,
blended at 18% into the base. Combined with the tighter smoothstep
(0.24 -> 0.18) the cloud silhouettes have more interesting edges
instead of soft blob shapes.
- Same density bump applied to clouds2d so swapping renderers
doesn't change the visual weather.
- config.renderer: clouds2d -> clouds3d (user request)
