/**
 * Variant CSS: before-after--duo-stacked-rows
 * Layer 2 — Path B before-after role (2026-06-10).
 * Exactly TWO full-width rows stacked vertically. Each row = a fixed-width LEFT
 * RAIL (big number + case title + a "Metamorfoza" eyebrow) and a wide
 * before|after split pair filling the rest of the row, every half carrying a
 * corner tag ("Przed" / "Po").
 * Distinct from stacked-register-pair (number + title inline at the START of the
 * row, then the pair) and twin-vertical-columns (two narrow columns side by
 * side): here the descriptor lives in a dedicated side-rail panel and the split
 * runs wide across the row.
