/* --------------------------------------------------------------------------
   ai-slop's stylesheet.

   The palette, the fonts, the mono-caps micro-labels, the 6px radius and the
   120ms transitions are calebstew.art's, so the two sites read as siblings.
   The layout is not: that site is two pages of prose, this one is a catalog of
   skills and the long documents they ship.

   House rules, if you edit this:
     - colours only ever come from the tokens below;
     - one content width, `--content-max`, on every page — a width that changes
       between page types reads as breakage, not as design;
     - no shadows and no sticky positioning: depth comes from a border and a
       background, movement is a 120ms colour transition, and that is all;
     - dark mode is `prefers-color-scheme` only. There is no toggle.
