/*
  Tooth menu + chart attribute panels (chart.html, tooth_menu.html).
  Everything is scoped under the cf- prefix so it cannot leak into the rest of the app.
  Sizes are in px on purpose: the chart page body is font-size: 40px (fs-pix-40) and the rest of the app
  uses percentage font classes, so em/rem would inherit that.
  Set --accent on any element to colour its dot, focus ring and checked state (category colours match the chart).
