/* =========================================================
   What How Why : the mock kit.

   Every "How" simulation is drawn with these classes, so a
   facilitator practising the register and one practising the
   marking app see the same quality of fake screen. Everything is
   prefixed m- and scoped inside .m-screen, so nothing here can
   leak into the training app's own chrome.

   --accent is set per module (the real app's main colour).
   The full list of classes is documented in MODULES.md.
