/**
 * Variant CSS: before-after--trio-vertical-split-columns
 * Layer 2 — Path B before-after role (2026-06-10).
 * Exactly THREE vertical columns. Each column = a numbered header bar (ordinal +
 * title) over a VERTICAL pair: the "before" photo sits directly ABOVE the "after"
 * photo, the two split by a strong horizontal seam, every frame carrying a corner tag.
 * Distinct from three-case-grid (loose stack, gap between frames, title-only on top)
 * and twin-vertical-columns (only TWO columns): here three transformations read
 * top-to-bottom and a hard horizontal seam separates the starting state from the result.
