/* ---------- Layered sections (floating "sheets") ---------- */
/* Increasing z-index puts each later section physically on top of the
   one before it. The section above overhangs the seam, so its shadow
   falls DOWN onto the top of the section that follows — an inset
   shadow set into the incoming section's own top edge, not a shadow
   bleeding upward into the section that's ending. A 1px lit rim sits
   right at the seam to read as the raised edge catching light. */
