  CALCULATOR TOOLBAR & SEGMENT STATES
  Colour/hover states for the toolbar buttons (.tbtn), option
  tiles (.it), segmented toggles (.sq-seg) and show/hide chips
  (.pd-hidebtn) that several tool pages define inline with their
  own layout. Prefixed with `main` so these win over the per-page
  copies; the pages keep their own sizing/spacing.

  The same three states everywhere:
    rest     — white, slate border, dark text
    hover    — brand teal fill, white text   (6.7:1)
    selected — pale teal fill, teal border, bold dark-teal text
  Primary actions (.accent) are teal and hover to navy.
