/* The shop drawing.

   Register: a workshop reference sheet, not a web app. Warm paper ground, ink
   linework, one sap-green accent, and every measurement set in a mono face
   because measurements come off a rule and want to line up in a column.

   Deliberately unlike its neighbours in this portfolio:
     print    achromatic, white, reference table first
     travel   mid-blue utility, horizontal time ribbon
     pdf      indigo, drop zone into a workspace
     home     the original calculator grid
   This one is warm, physical, and built around a drawing that changes.

   The board art carries its own wood tones and they are the only place strong
   colour appears. Chrome stays out of its way.
