/* Good Vibe Games — the one look every page shares.
 *
 * Beige paper, soft ink, a rounded typeface, and the sun and the leaf kept
 * for the things you can press. This is Good Vibes' own page theme, promoted
 * to the whole site: three of the pages here were already set in exactly
 * these values, and the other seven had each grown a dark theme of their own
 * — a dark brown shelf, a dark green greenhouse with green type on it, a
 * black space chart. The values are the same ones for the same reason
 * pixel.js keeps one palette for the games: a colour can only be changed in
 * one place, which is the only way a look stays one look once there are ten
 * screens.
 *
 * Every page still keeps its own <style>, and most keep their own token names
 * — a page that calls the ground `--ink` and one that calls the ink `--ink`
 * cannot share a vocabulary without a rewrite nobody needs. Each one aliases
 * its names onto these, so the numbers live here and the names stay local.
 *
 * Contrast is measured against --gv-paper: text 13.8:1, muted 5.6:1, leaf
 * 5.0:1, sun 5.0:1, sky 5.9:1, bad 5.2:1 — every colour used as text clears
 * the 4.5:1 body text needs. The two bright surfaces, gold and soft leaf, are
 * for buttons with dark type on them and are never text themselves.
 *
 * Nothing is loaded from anywhere: this is a file in public/, and the type is
 * a system stack — `ui-rounded` is SF Rounded on Apple, where most of the
 * phones are, and the platform's own humanist face everywhere else.
