 * .MD — Shortwave Station
 * Source of truth for the platform's visual world.
 *
 * The previous system was gold on a warm near-black (oklch hue 55 — orange). Reviewed as
 * "heavy"; replaced with a night-propagation field at hue 255. Shortwave skywave actually
 * propagates at night, so the blue-black is the world's material, not a preference.

 * Colour discipline: signal blue carries the interface. Amber phosphor marks ONLY what is
 * currently tuned. Red marks ONLY what is live/on air. If amber or red appear anywhere
 * they do not encode state, the instrument has become decoration.
