/* Sonar — crimson-on-black trading HUD.
 *
 * Matched to the reference: near-black ground, one crimson primary carrying
 * glow, hairline red panel borders, monospace ALL-CAPS technical labels, dense
 * readouts. Rounding is kept from the earlier brief — the reference rounds its
 * pills fully and its panels softly, so the two are compatible.
 *
 * DARK ONLY, on purpose. A light-mode cyberpunk HUD is a contradiction, and a
 * `prefers-color-scheme: light` variant would have to invent a second palette
 * that matches nothing.
 *
 * Colour discipline, which is what keeps this from becoming noise:
 *   --accent (crimson) is CHROME — borders, focus, the top tier, the price
 *   line. The categorical hues (--gold, --magenta) are DATA ONLY: they mark
 *   tier and horizon, never decoration. Nothing else is coloured.
 *
 * Motion carries meaning: cards stagger so the eye gets a reading order, bars
 * grow from zero so length is felt, the scanline sweeps only while a scan runs.
 * All of it dies under prefers-reduced-motion.
