   COLOR WHEEL — /color-theory (prefix ctg-)
   The tool-guide design system (docs/design/tool-guide-design-system.md) around
   the colour wheel: a MONO hero with the tool right under it and one-line
   stats; the long colour-theory editorial keeps its own typography inside the
   rail; then the lime bento, the dark library card, the FAQ accordion and the
   other tools. The tool itself keeps its cw- rules; .ctg re-dresses the shell.
