/* ===========================================================================
   Classification dashboard theme.
   Tokens and primitives. Page layout lives in app.css, which loads after this.

   Read THEME.md before you add a component. Two rules matter most:
     1. Use a token. Do not write a hex value in app.css or in page CSS.
     2. Colour never carries meaning alone. Pair it with a glyph or a label.
