   struckmatch.studio — THE BLACK ROOM

   One room. One light. The guitars stand together on one floor, close
   enough that a falling one would catch its neighbour. The key is a single
   hard source from the upper left over the WHOLE room — never one lamp per
   guitar. Empty stands take the same light and simply stand darker, which
   is how the season shows itself filling up.

   Built from v3/LOOK.md. Every colour here is black, the light, or gold.
