/**
 * Variant CSS: before-after--duo-slider-frames
 * Layer 2 — Path B before-after role (2026-06-10).
 * Exactly TWO cases, each a single comparison frame: a "Przed" half | a faux
 * vertical slider grip (track + circular knob with ‹ › arrows) | a "Po" half.
 * The two photos kiss either side of the grip, reading as one draggable slider
 * (purely static — no JS). Below each frame: a number + case title.
 * Distinct from center-seam-pair (one thin spine dividing the WHOLE section into
 * two halves, no knob) and slider-divider count-1 (a single frame): here there
 * are two independent frames, each with its own grip handle.
