/*
 * The site's own rules. Everything that could come from brand-core does —
 * this file holds only layout and marketing-page typography, which the design
 * system has no opinion about. No colour literal appears here: every value is
 * a brand-core token (var(--*)).
 *
 * Contrast: --text-mute and --blue-as-text fall under WCAG AA (4.5:1) on
 * several light-theme surfaces, so readable text here uses --text-dim and
 * links use --blue-bright, which clear 5:1 on every background in both themes.
 *
 * Load order (see src/layouts/Base.astro): reset, tokens, fonts, primitives,
 * then this, so these rules win a specificity tie.
