/* Memory design tokens: monochrome.
   Pure neutrals, no accent colour. Emphasis comes from weight, size, inversion
   and space; hue is reserved for status (success, warning, danger), always with
   an icon or label. One source for every page (marketing, docs, legal, dashboard).
   theme-init.js always sets data-theme="light" | "dark" on <html> before first
   paint; the media query below only covers the no-JS case.
   Contrast pairs are checked by tests/test_design_tokens.py. */
