/* ─────────── DM Sans self-host scaffold ───────────
   To remove the Google Fonts dependency:
   1. Download these 6 woff2 files (https://fontsource.org/fonts/dm-sans is the easiest source):
        - dm-sans-latin-300-normal.woff2
        - dm-sans-latin-400-normal.woff2
        - dm-sans-latin-500-normal.woff2
        - dm-sans-latin-600-normal.woff2
        - dm-sans-latin-300-italic.woff2
        - dm-sans-latin-400-italic.woff2
      Drop them in `fonts/dm-sans/`.
   2. Uncomment the @font-face block below.
   3. In each HTML file, remove the <link href="https://fonts.googleapis.com/...">
      and the two <link rel="preconnect"> lines for fonts.googleapis/gstatic.
   4. Remove the Google Fonts paragraph from privacy.html (Section 9).
