/* Today's Cure · home "Begin with Mind Cures" 3D bookshelf (tcshelf1 2026-11-01; tcshelf2 hover pop-out; tcshelf3 2026-11-02 real-book look).
   Mind Cures, Body Cures, Soul Cures stand free in a row. Only Mind Cures opens. Pure CSS 3D + /assets/js/shelf.js, no libraries.
   tcshelf3: hardcover boards with squares over a cream page block, rounded spine (5 facets, one continuous print + light),
   concave fore edge, headbands, cloth/paper grain (tiny inline PNGs), contact shadow + ambient occlusion, slight natural lean.
   GENERATED: edit tools/shelf3/shelf.src.css, then python3 tools/shelf3/gen_geom.py. Own section below the June 1 feature panel.
   Without JS (or if shelf.js fails) the whole section stays hidden. */
