/* ═══════════════════════════════════════════════════════════════════
   TACTIC: Work, layout B, the bookcase
   Shelf rows of books standing upright. Closed, a piece is a vertical
   spine: a sliver of its own footage, its type running bottom to top.
   Roll across the shelf and one book opens laterally into the film at
   its own 16:9 ratio, captioned in a clear band beneath the frame.
   Row height never changes, so nothing on the page ever jumps.

   Loaded by work-b.html only, after styles.css / styles-v3.css.
   Tokens come from styles.css (:root).

   shelf board line, no category dots (category is named in words).
   Labels use the shared mono spec; the caption title is a --d3 subhead.
