 * Source Sans 3 (Adobe, SIL Open Font License 1.1), self-hosted. Never load a
 * font from a CDN — see the privacy requirements in CLAUDE.md.
 *
 * Two variable files cover every weight the site uses (400/500/600/700/800/900)
 * plus italics. Regenerate the subsets with `node scripts/subset-fonts.js`;
 * the licence text sits next to the files in website/static/fonts/.
 *
 * The URLs are relative, not absolute. This stylesheet lives at /css/site.css
 * and the React bundle's stylesheet at /app/index.css — both one level deep —
 * so `../fonts/…` resolves identically from either, and survives any baseURL
 * change without touching the paths.
 *
 * ─────────────────────────────────────────────────────────────────────────── */

/* `font-weight: 200 900` declares the variable axis range, not a single weight.
   The files' own default instance is 200 (ExtraLight), so anything that renders
   the font without resolving a weight comes out alarmingly thin — if you ever
   see that, the cause is a missing font-weight, not a broken font.

   Plain `format('woff2')` is deliberate. The older `woff2-variations` hint is
   only needed for browsers that predate variable-font support entirely; every
   engine that can render these files detects the axes from the file itself. */
