/* AppSystem design system — plain CSS, no build step.

   Tokens first (colours, radius, spacing, type), then components. Pages use the component
   classes (btn, field, select, card, toolbar, data table); they never hard-code colours.
   A theme = another set of tokens: add `:root[data-theme="<name>"] { ... }` below and set
   data-theme on <html>. Loaded after utilities.css (frozen layout utilities); see docs/ai/UI.md. */
