/**
 * Light Studio
 *
 * The room is one photograph. Everything else is painted over it, inside one
 * isolated group so every blend mode composites against the room:
 *
 *   0. The room, exposed by one number, --dls-light, which the script computes
 *      from the lamps AND the time of day. A dark room is not a dim copy of a
 *      lit one — it is darker, flatter and nearly colourless — so exposure moves
 *      brightness, contrast and saturation together.
 *   1. Glass. Lamps never light the garden: outside follows the time of day on
 *      its own, and at night the pane becomes a faint mirror of the interior.
 *   2. Signature layers — where each fixture's light falls, screen-blended.
 *   3. The star ceiling, drawn on a canvas clipped to the ceiling plane.
 *   4. Luminaires, drawn as SVG. Cores burn toward white; colour is in the halo.
 *   5. A tint tipping the white balance toward the lamp temperature.
 *
 * Every position is a custom property. The defaults are traced from one
 * photograph; a buyer's room has its ceiling and windows somewhere else, so all
 * of it can be overridden per instance without touching the markup.
 *
 * No theme dependency: every value is defined here.
