/* ---- Palette ----------------------------------------------------
 *
 * Two complete palettes (light / dark). The "active" variables at the
 * bottom of :root point at one or the other and get re-pointed by:
 *   - @media (prefers-color-scheme: dark)          — automatic
 *   - html[data-theme="dark"]                      — manual override
 *   - html[data-theme="light"]                     — manual override
 *
 * Reports are excluded from dark mode because PDF/HTML exports are
 * meant to be printed and shared on unknown backgrounds — the
 * body.report selector at the bottom locks them back to the light
 * palette regardless of the active theme.
