/* coe.css: the Centre of Excellence design system (docs/SPEC.md section 10).
 *
 * The reference is Apple Intelligence: a black ground, one clean sans in tight, confident sizes,
 * soft floating cards with large corners, frosted glass for anything that sits over the page, and
 * one piece of colour: a slow, soft spectrum of light (amber, pink, violet, blue) that marks what
 * matters most on a screen. Everything else stays quiet, so the light means something.
 *
 * There are no inline styles anywhere (the CSP forbids them), and the spectrum is defined once,
 * here, so that the ring, the ambient light and the chart agree.

 *   - every colour that carries text is at least 4.5:1 on --ground and --card, and the tinted panels
 *     carry only colours that are 4.5:1 on them (WCAG AA); form field borders are at least 3:1
 *     (WCAG 1.4.11). --hair is decoration and stays quiet.
 *   - no text below 0.75rem (12px) outside print.
 *   - all motion stops under prefers-reduced-motion.
