   FONTS
   Embedded as data URIs so this mockup renders correctly when opened straight
   from disk — Chrome blocks file:// font requests otherwise.

   FOR THE REAL BUILD: delete this block and use the file-based rules instead.
   The .woff2 files are already in assets/fonts/ and the rules look like:

     @font-face{font-family:Figtree;font-weight:800;font-display:swap;
       src:url(../fonts/figtree-800.woff2) format("woff2")}

   Both families are OFL. Figtree stands in for the deck's display face, which
   is still to be identified and licensed — see the brief, §5.
