/*
 * The palette is derived from `public/symbol.svg`, the pixel-art sarué face.
 * The symbol uses exactly five colours, and three of them are used here
 * unchanged: black #000, tan #ad8653, white #fff, peach #ffc2a8, grey #afafaf.
 *
 * Two derivations were forced by measured contrast rather than taste:
 *
 * - `--accent` is the peach hue darkened to #8f4a26 (6.34:1 on the page), because
 *   the icon's own tan reaches only 3.19:1 and cannot carry link text.
 * - the peach button ground is only 1.49:1 against the page, so the primary
 *   button takes a border in `--accent` to keep its boundary identifiable.
 *
 * The greys are neutral, following the icon, and the warmth lives entirely in
 * the peach and tan accents — the same proportion the animal has.
 *
 * The typeface is Atkinson Hyperlegible Next, commissioned by the Braille
 * Institute and drawn so that similar characters cannot be confused. It is
 * self-hosted from this domain — no third party is contacted to render a page.
