/* Studio design system 2026.11.08. Built from websites/design-system/src by build.py; edit the sources. */
/* Studio design system: tokens.

   Forked on 2026-11-08 from the CommunityScale design system (app/design/tokens/tokens.css and the rules in
   app/design/web/): the same spacing, 12-column grid with 32px gutters, card, button, and header conventions.
   The owner's changes: system fonts only, grayscale by default, the grays of nelsoki (studio/websites/nelsoki,
   a Flexoki variant with a neutral ground; Flexoki is Copyright (c) 2023 Steph Ango, MIT License, notice in
   nelsoki/README.md) with a gray page rather than white, and square corners. A site that wants a color sets
   --ds-accent (and, if it needs them, the status colors) in its own stylesheet; nothing else takes a hue.

   Light values sit on bare :root. Dark values are set twice, under [data-theme="dark"] (what ds.js sets) and
   under prefers-color-scheme for a page without the script, guarded so an explicit light choice wins. */
