/* UIX Icons design system v2. Load AFTER brand/tokens.css and BEFORE page CSS. Docs: src/site/ds/DESIGN.md.
  Modern clean SaaS: flat surfaces, hairlines, bento grids. Tactility only as accents (keys, plates, one glass, the mark).
  Colours use light-dark(): the theme is the element's color-scheme (light by default, dark from the system,
  <html data-theme>, or any .ux-dark band / dark tile).
