/* ===========================================================================
   Kimberley College password kiosk
   ---------------------------------------------------------------------------
   The design is the absence tracker's, and the tokens below are copied from
   it rather than re-chosen: the lit navy ground, one glass card floating on
   it, Poppins over Open Sans, laurel green for the action, maroon once for
   emphasis. If a colour changes there it should change here.

   What is different is who uses it. The tracker is read at a desk by staff
   all day. This is used standing up, once, by a student who is slightly
   stressed and may be seven. So: one card, one question per screen, controls
   large enough for a touchscreen (nothing interactive under 48px tall), and
   text sizes a step up from the tracker's throughout.

   The same contrast rule holds: glass on the chrome, solid under anything
   that has to be read. The card is 96% opaque for that reason.
