   VaniQ — the shared surface.

   One canvas, one typeface, one accent. The page is dark because the product
   is: VaniQ lives in the menu bar and draws a dark HUD over whatever you are
   working in, and a bright marketing page would be a different object than the
   thing it sells.

   The typeface is the system one on purpose. This is a Mac-only app, so every
   qualified visitor renders San Francisco — the same face as the app, macOS and
   apple.com. No webfont request, no flash of fallback, nothing to load before
   the first paint.
