/* ---------------------------------------------------------------------------
 * Font face: Inter (self-hosted, variable font)
 * ---------------------------------------------------------------------------
 * TEMPORARY CDN FALLBACK: assets/fonts/inter/ only ever contained a
 * README placeholder — the two real .woff2 files were never actually
 * added to the theme package, so every @font-face below was 404-ing and
 * the whole site was silently falling back to the browser's default
 * sans-serif. This is the actual cause of "Inter isn't used anywhere" —
 * it's not a CSS bug, the font files simply don't exist on disk yet.
 *
 * Each rule below tries the local (self-hosted) file FIRST, then a
 * Fontsource CDN copy as a fallback — browsers move on to the next src
 * when one 404s, so this renders in Inter right now and will
 * automatically prefer the faster self-hosted file the moment the two
 * real files are uploaded. No further CSS change needed at that point.
 *
 * TO REMOVE THE CDN DEPENDENCY: drop the two real files here, then
 * delete the extra jsDelivr url() line from each rule below:
 *   assets/fonts/inter/InterVariable.woff2
 *   assets/fonts/inter/InterVariable-Italic.woff2
 * Get both from https://rsms.me/inter/ ("Inter Variable" download) or
 * https://github.com/rsms/inter/releases.
