13Times: `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.

15The 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.
