/** * Site-wide stylesheet. Palette/type from the 2026-09 homepage redesign * brief — warm ivory as the main background, burgundy as an ACCENT (never a * large fill), terracotta and olive as sparing secondary accents, Cormorant * Garamond + Inter. See src/components/Header.astro, Footer.astro, * src/pages/index.astro for how these get used, and README's "2026-09 * homepage redesign" section for the full brief and the reasoning behind * each token below. * * PALETTE HISTORY: this replaces an earlier oxblood/parchment/brass system * (dark burgundy header/footer/hero, Fraunces + Karla) — same variable * NAMES kept deliberately (--oxblood, --parchment, --ink, --brass…) so every * existing consumer across the ~20 files that reference them picks up the * new palette automatically, with zero risk of an unrenamed straggler left * on the old colors. Only genuinely new roles (--terracotta, --olive) got * new names; the dead --sage (0 usages, confirmed by grep) was removed * rather than repointed, since --olive replaces its intended role cleanly. * * CONTRAST, MEASURED NOT ASSUMED (relative-luminance WCAG formula, every * pairing below computed before use, same discipline as the earlier * --brass fix this file already documents further down): * charcoal/burgundy on ivory or white: 8.7:1-15.0:1 (AA, both sizes) * ivory on burgundy (primary button, header): 8.7:1 (AA, both sizes) * terracotta AS TEXT on ivory or white: 3.0:1-3.3:1 (FAILS AA-normal, * and fails even AA-large against ivory) — so terracotta never carries * running text here, only borders/fills/small marks, exactly what the * brief itself asks for ("use terracotta and olive only as subtle * secondary accents"). * olive AS TEXT on ivory: 4.4:1 (fails AA-normal * by a hair) — same treatment as terracotta: decorative only. * ivory/white text on a terracotta fill: 3.0:1-3.3:1 (FAILS) — so the * brief's "hover: terracotta" is implemented as a terracotta fill with * --ink (charcoal) text, not ivory text: charcoal-on-terracotta measures * 4.52:1, clearing AA-normal. See .wnh__btn:hover in index.astro. * * faq.css's rules now live in FaqAccordion.astro's own
