/* Humboldt design system. One stylesheet for every Humboldt surface: the pages in this repo import it, the
   product server's pages (integrations, connect, sign-in) link it from the Humboldt host, and the docs on
   Mintlify carry the same tokens in docs.json.

   Grounds   paper and ink; the dark theme inverts them (the sun/moon toggle, or the system's preference).
             Dark is also a material: a dark sheet or frame on a paper page carries a film grain.
   Type      Newsreader for everything read (display 400, body 400, one weight for emphasis 500).
             JetBrains Mono for everything that is not prose: labels, buttons, facts, code. Labels and buttons
             are mono, uppercase, letter-spaced.
   Geometry  1px rules in the rule colour; 4px on buttons and chips, 12px on frames; no shadow except the
             frame's; no gradient anywhere.
   Copy      one headline of eight words or fewer and one sentence of thirty or fewer per section; the product
             itself (a thread, a terminal, a row) carries the rest. Titles are the noun alone.
   Motion    the cover rises once on load; sheets stack on scroll; nothing else moves. Reduced motion: nothing.
   Marks     a provider's mark is monochrome, 40px, in the ink; Slack's four colours appear only on the official
             Add to Slack button. */
