/* Health AIO design kit: components. Part of the kit (see docs/DESIGN_KIT.md).
   Every colour comes from tokens.css, and so does every margin, padding and gap that is a step of the space scale
   (tests/test_kit.py checks both). Other sizes are plain numbers: the fixed heights of controls (30px pills, 24px
   chips), insets off the scale (2, 3, 5, 6, 9, 10, 14px), corners of 3, 4 and 6px and the demo badge's 11px type.
   Nothing here names a Health AIO page.
   Every group starts with a comment "@component <class> <one line>"; `healthaio kit json` lists them and the
   gallery (#kit) shows each one. Page-only rules live in the app's own stylesheet (Health AIO: app.css). */
