/* ==========================================================================
   NOTE ON BUILD
   This file is the single source of truth AND what WordPress serves. The
   source is kept readable (comments + whitespace); minify on deploy if you
   want the last few bytes. The whole page is one viewport, so we load this as
   one small, render-blocking, same-origin file rather than splitting critical
   CSS — there is no meaningful "below the fold" to defer for a single screen.
   ========================================================================== */

/* ---- Self-hosted display font (variable, subset, swap) ------------------- */
/* Fraunces is bundled. The UI font (--font-ui) deliberately rides the system
   sans stack — zero bytes, instant. To self-host Inter instead, add an
   @font-face for "Inter" here pointing at a subset assets/fonts/inter-*.woff2;
   the token already lists "Inter" first so it'll take over automatically. */
