/* ============================================================================
   milling-simulator / demo.css

   Every colour is a token from msu-theme.css; nothing here defines one.
   Gold and red-orange are fills and strokes only, never text (contrast
   rules 1 and 2 in the token layer). Control shapes follow the other
   machining labs, so this reads as one of them.

   The finished part uses the lathe lab's language: the drawing's outline in
   --cat1, metal still to remove in --cat2, metal cut past the drawing in
   --cat3. The block itself is grey. Gouges are striped as well as coloured,
   and every state is also named in words (legend, status, inspection).
