/* ============================================================================
   Beyond the Line — Decal Lab (decal-lab.html)
   ----------------------------------------------------------------------------
   Loads AFTER site.css and theme.css and only adds the page that is not on the
   main site: the editor shell, the picker grids and the proof pane. Colour
   tokens, buttons, .input, .field-label and .swatch-row all come from those
   two files, so this page cannot drift away from the rest of the site.

   The shell is one screen tall on a laptop — controls on the left, the decal on
   the right — and stacks to proof-then-controls on a phone, so the thing being
   designed is the first thing in view.
