## Description

Time of day and atmosphere in Blender 5.2 - measured sky + sun for dawn, morning, noon, golden hour, sunset, blue hour, overcast, night/moonlight with stars and city glow, exposure balance, height fog from visibility, god rays, Cycles vs EEVEE volumes, compositor grade, stylized moods (cyberpunk neon, horror, underwater, desert). Use for any day/night, sunset, foggy or mood lighting scene.

# Time of Day & Atmosphere

The execution model is in `blender-core`. Studio and product lighting are in `blender-lighting-lookdev`, render settings in `blender-rendering`, and rain, snow, wetness and lightning in `blender-weather-fx`.

## One call
```
scripts/scene_mood.py -- --time golden                       # sun 6 deg, warm, long shadows
scripts/scene_mood.py -- --time night --fog-visibility 250   # moonlight + stars + haze
scripts/scene_mood.py -- --time noon --overcast 0.8          # soft grey day
scripts/scene_mood.py -- --mood cyberpunk                    # moonless, neon rim pair, fog, bloom
scripts/scene_mood.py -- --time morning --fog-visibility 120 --fog-height 4   # valley fog
```
Times: `noon morning afternoon golden sunrise sunset blue_hour night moonless`. Moods: `cyberpunk horror underwater desert` (each sets defaults that explicit flags override). Override the sun with `--elevation DEG` (negative = below the horizon) and `--heading DEG` (0 = +Y, 90 = +X). If you leave out `--heading`, the sun sits 135° from the camera's view direction, which gives side/back light that shows form. Front light looks flat.

The script builds `ENV_World`, the `ENV_Mood` collection (sun or moon, fog box, accent lights) and, for moods, `ENV_Grade` (a compositor tree). Your objects are untouched, and re-running replaces everything it made. It returns the key light's strength, color and elevation, the exposure, and any warnings.
