/**
 * Variant CSS: before-after--seam-quad-board
 * Layer 2 — Path B before-after role (2026-06-10).
 * One panel split into FOUR quadrants by a central cross-seam (a "+" where the
 * two rows of two meet). Each quadrant = a numbered VERTICAL before-over-after
 * stack (two landscape frames, corner tags) plus a bound project title.
 * Two columns rows are butted together (gap:0) inside a bordered board, and a
 * crosshair is painted over the centre so the four cases read as one board.
 * Distinct from quad-grid-cards (separate bordered cards, horizontal splits)
 * and compact-quartet-columns (four slim columns in a strip): here it is a
 * single unified quadrant board.
