/* ============================================================
   Showroom, phase 0.5.

   Larina Open Frame, brand system 3.2 EN. The six brand colours are
   declared once and everything else names a role, so this prototype
   cannot drift away from the identity while it is being hacked on.

   Layout: a big picture, the catalogue beside it, the tools out of
   the way. Handles appear only while the floor is being adjusted.
