   SELF-HOSTED FONTS
   Downloaded latin subsets only — no Google Fonts CDN needed.
   DM Sans and Playfair Display are variable fonts so each
   weight declaration shares the same woff2 file.

   font-display: optional — with rel=preload the font is ready
   before first paint so it's used immediately with zero CLS.
   On the rare case it misses the window the size-adjusted
   fallback faces below minimise any reflow.
