- * `room-shelves.png`, read off the painting: six shelf rows, four volumes on
- * each, spread along the row and kept clear of the ladder and the sleeping cat,
- * which are the two things on that wall that are not books. Archiving darkens
- * the painting inside one of these rectangles, so the volume that stands out is
- * a volume the painter put there.
+ * Each rectangle is one BAY of the wall — the run of books standing between two
+ * posts on one shelf, from the ledge up to the shelf above it. It used to be one
+ * spine, four to a shelf and spread along it, and however much work had been

+ * fill, and a filled bay is a thing the eye counts where a single darkened spine
+ * among dark spines is not.
  *
- * The order is the order they are handed out in — along each shelf, top row
- * first, which is how a wall of books fills.
