/* * Hazen Studio design system * ────────────────────────── * One stylesheet for every site under hazenstudio.com: the portfolio, the * MacLC website and each live demo. Served at /hazen/hazen.css and documented * in docs/design-system.md. * * - Everything sits in the cascade layers Tailwind CSS v4 uses (theme, base, * components, utilities), declared in Tailwind's order. Tailwind's preflight * then resets elements before the hz-* components apply, Tailwind utilities * override the components, and a site's unlayered CSS overrides everything. * Link this file FIRST in , before any other stylesheet. * - Colours follow the theme on , set before * first paint by the snippet in the docs. Without JavaScript they follow * prefers-color-scheme. Any element can carry data-theme to force a theme on * its subtree. * - One accent per site, picked with . The default * is amber, MacLC's highlight. Accent fills always take --hz-on-accent * (near-black) text; --hz-accent-text is the contrast-safe variant for text * on the page. Every pair passes WCAG AA in both themes. */ /* ─── Fonts ──────────────────────────────────────────────────────────────── Geist (text and UI), Geist Mono (labels and figures) and Instrument Serif (the italic emphasis in headlines).
