/**
 * Variant CSS: before-after--vertical-stacked-reveal
 * Layer 2 — Path B before-after role (2026-06-06).
 * One dramatic case stacked vertically: full-width "before" frame ABOVE the
 * "after" frame, joined by a centred seam pill ("Nasza praca") that reads as
 * the moment of transition. Distinct from the column variants (side-by-side /
 * three-stage / case-grid): the eye travels top -> bottom through a single
 * transformation, the seam chip marking the cut.
