   FONT CONFIGURATION
   ──────────────────────────────────────────────────────────────
   Swiss 722 Std Bold Condensed is a commercial typeface (Bitstream /
   Monotype). It is not on Google Fonts and must be licensed.

   To configure it:
     1. License the font at: monotype.com, myfonts.com, or adobe.com/fonts
        (search "Swiss 721 Bold Condensed" or "Swiss 722 Std Bold Condensed")
     2. Place the font files in the /fonts directory:
          fonts/Swiss721BT-BoldCondensed.woff2
          fonts/Swiss721BT-BoldCondensed.woff
     3. Uncomment the @font-face block immediately below.

   Until the font files are in place, headings fall back to:
   'Arial Narrow' → 'Franklin Gothic Condensed' → Impact → sans-serif.
   Arial Narrow is a reasonable structural stand-in while you configure
   the real font.
