/**
 * Variant CSS: gallery--stacked-offset-pair
 *
 * Two wide frames stacked one above the other, the second shifted sideways from
 * the first (hover zoom) — a stepped layout with captions on the open margin.
 * Unlike two photos side by side: a vertical stack with an offset walks the eye
 * down in a zigzag, like a magazine spread. The lead row hugs the left; the second
 * row is indented from the right, each image capped below full width so the caption
 * sits in the freed margin. Text stays --ink (polarity aware); kicker + the em +
 * the caption tick take --accent; images carry --photo-filter. Image src are
 * swapped by the photo system. Dedicated to exactly two photos. Part of the
 * `gallery` role.
