/* radar.css — Boojee Problem Radar.
 *
 * ⚠ THE GRADE MUST NEVER BE CARRIED BY COLOUR ALONE. "five people said this
 * independently" and "one person said this" are the only claims on the page
 * that matter, and the whole tool is worthless if a reader skims past the
 * difference. Each grade therefore carries a word, a border style AND a
 * colour, so it survives greyscale, colour blindness and a fast scroll.
 *
 * ⚠ `single` is deliberately NOT styled as a failure. It is the honest and
 * most common answer. Styling it as an error would push a future me toward
 * loosening the clustering to make the page look healthier, which is exactly
 * how this tool would start lying.
