   THE VISITOR  /  SYSTEM  v0.2  (Nov 2026)

   Tokens, type, space, margins, buttons, section header, card.
   The future top of styles.css. Nothing in here is page-specific.
   If a value isn't a token, it doesn't exist.

   v0.2: no serif. One grotesk (Switzer) for everything you read,
   one pixel monospace (Departure Mono) for everything you scan:
   labels, numbers, coordinates, meta. White and grey text. One
   signal orange, reserved for the dither and for the moment you
   touch something. One shape: the cut corner.
