/* ============================================================
   FONTS — DM Sans, self-hosted variable font
   Files live in assets/fonts/. Licence: SIL Open Font License
   (free to self-host commercially). Source: Google Fonts v17.

   Self-hosted rather than loaded from the Google Fonts CDN: it's
   faster (no third-party DNS + TLS handshake), and it keeps our
   visitors' IP addresses away from Google.

   VARIABLE FONT — one file covers every weight from 100 to 1000.
   That means:
     - two files total instead of one per weight
     - any weight is available, including in-between values
       like 450, at no extra download cost

   Split by character coverage, not weight:
     dm-sans-latin.woff2      37KB — English and most Western European
     dm-sans-latin-ext.woff2  18KB — extended Latin (accents, currency)

   The `unicode-range` descriptors mean the browser downloads
   latin-ext ONLY if the page actually contains one of those
   characters. Most visitors will only ever fetch the 37KB file.
