/* =====================================================================
   FONTS
   ---------------------------------------------------------------------
   The design uses three typefaces:
     • The Acres Sans  (uppercase display — hero headline, section labels)
     • Neue Grand 53 Regular Wide (body copy, headlines, buttons)
     • Geist            (nav menu, "Play video" label)

   Geist is free (loaded from Google Fonts).
   "The Acres Sans" and "Neue Grand" are COMMERCIAL fonts. To get a true
   1:1 match, drop the licensed web files into the /fonts folder and
   uncomment the @font-face blocks below. Until then the closest free
   grotesque (Archivo) is used as a stand-in via the font stacks.
