/**
 * Variant CSS: before-after--center-seam-pair
 * Layer 2 — Path B before-after role (2026-06-10).
 * One bordered board split by a SINGLE central vertical seam into two sides —
 * a left case and a right case meeting on a shared spine, like a spread. Each
 * side = a number + title head, then a HORIZONTAL before|after pair with corner
 * tags.
 * Distinct from duo-split-cards (a seam INSIDE each separate card) and
 * seam-quad-board (a cross "+" seam for four quadrants): here one centre seam
 * divides the whole section into two halves.
