/**
 * Variant CSS: before-after--quad-split-rows
 * Layer 2 — Path B before-after role (before-after count-4 expansion 2026-06-10).
 * FOUR full-width rows. Each row = a slim left rail (big ordinal over the bound
 * project title) followed by an edge-to-edge "Przed | Po" split whose two halves
 * kiss on a labelled centre seam (a thin divider carrying a small "→" marker).
 * Distinct from register-rows-quad (small index + title-left + a plain compact
 * pair on the right, no seam) and quad-grid-cards (a 2x2 of bordered cards):
 * here the four cases read as a wide, cinematic register of seam-splits.
