/* ── the shelf, as physical books ──────────────────────────────────────
   Each cover is the front face of a box; the spine is a second face folded
   back along the left edge at the real 0.5in : 8.5in ratio. The books sit at
   a slight resting angle so the spine is always a little visible — that is
   what stops them reading as flat cards — and the tilt deepens on hover.  */
