/* Audio Audit. Loads after groups.css; the panel uses the shared .nd-panel / .nd-top / .nd-controls styles and the Crate tokens.
   The stage is a CHALKBOARD in a wooden frame in every theme, so the zone colours always read from the back of a room.
   Zone colours are the five highlighters (sky, leaf, sun, tomato) and are never the only signal: the words, the number, the number of
   lit crates and the limit line say the same thing. Everything is flat: solid fills, chalk outlines, hard offset shadows. */
