   sniffi.ai — shared site styles.

   Dark grey rather than black, and aimed at "instrument" rather than
   "mysterious": near-neutral greys, one gold accent, high contrast and a
   lot of empty space. The illustrations are light artwork, so they sit on
   the dark page as white cards, the way slides sit on a dark deck.
