/* ==========================================================================
   Woopcode docs — components.
   ==========================================================================

   Six components, each one earned by a page that needed it. Diff and state
   colours come from the tokens generated out of tui/src/styles/theme.ts, so a
   diff in the docs and the same diff in the terminal are the same colours.

   The restraint rule still applies here (system.md §5): no icons, no filled
   pastel boxes, no shadows. A component is a hairline, a rule, and type. */
