   BOOKCRATER APP — product surfaces
   Loads AFTER css/bookcrater.css, which owns all tokens and shared
   primitives. Nothing here redefines a token or introduces a raw colour;
   every value below resolves through the shared system.

   Surface intent (Round 1.7):
     workbench  = what do I do next
     lessons    = reading first
     mechanisms = physical field instruments
     toolkit    = practical equipment case
     tools      = numerical / decision instruments
     mobile     = field tool
