/**
 * Variant CSS: before-after--trio-diagonal-split-cards
 * Layer 2 — Path B before-after role (2026-06-10).
 * Exactly THREE cards, each ONE frame cut by a diagonal: the "before" photo is the
 * base; the "after" photo sits on top, clip-pathed to the top-right triangle so the
 * two states meet on a corner-to-corner seam. Labels sit in OPPOSITE corners
 * (Przed bottom-left over the before half, Po top-right over the after half); a
 * numbered title bar sits beneath.
 * Distinct from three-case-grid (a vertical stack of TWO separate frames) and
 * trio-pair-cards-row (a horizontal seam, two photos side by side): here both
 * states share ONE frame split on the diagonal, like a single composited photo.
