/**
 * Variant CSS: before-after--duo-diagonal-split
 * Layer 2 — Path B before-after role (2026-06-10).
 * Exactly TWO cases side by side. Each case = a single frame holding two stacked
 * photos cut by ONE diagonal seam (top-right corner to bottom-left corner): the
 * "Po" (after) shows in the upper-left triangle via clip-path, the "Przed"
 * (before) shows through the lower-right triangle beneath. A thin white diagonal
 * line marks the seam; labels sit in opposite corners. Number + title below.
 * Distinct from diagonal-reveal count-1 (a single frame) and center-seam-pair (a
 * straight VERTICAL seam between two halves): here two frames, each fused by a
 * diagonal cut.
