/* radar.monosoftware.xyz
 *
 * Built on shadcn/ui's token contract: the same semantic names, the same oklch
 * values for the neutral scale, the same radius scale, and the same component
 * anatomy (card header/content/footer, primary/outline/ghost buttons, badges,
 * input group, switch, toggle group, select, separator, field rows).
 *
 * Both themes are real: light is the default document theme and `.dark` on
 * <html> swaps every token. Nothing here is a dark design with a light filter -
 * text, borders, shadows, the canvas plate and the contact palette each have a
 * value per theme.
 *
 * Canvas colors are NOT taken from the oklch UI tokens. Canvas needs a string
 * it can parse on every engine, so the four instrument colors live as hex/rgba
 * in --radar-* and app.js reads them back with getComputedStyle. UI tokens stay
 * in oklch where only CSS consumes them.
