   GLOBAL STYLES — RESTYLE PASS (extracted from itsabdullahqureshi.com)
   --------------------------------------------------------------------------
   Tokens (color / type / space) are derived from the original Framer site's
   compiled CSS. Dark teal theme: near-black teal background, off-white text,
   cyan + teal-blue accents. Fonts are self-hosted (public/fonts/), Inter for
   body and Poppins for display/headings.

   Organized by token system first, then base elements, then component classes
   so each block maps back to the markup.
