   TheYgent — marketing site
   A dark, canvas-native design. The page lives on the app's real working surface:
   a dotted grid, ambient washes, the token surface ladder, and the logo's faceted
   polygon grammar as the only decorative motif. Sans (Geist) is human prose; mono
   is anything a machine addresses (logical ids, ports, the binding enum, hashes).
