/**
 * Variant CSS: gallery--overlap-float-pair
 *
 * One large base photo with a second, smaller photo floated over its bottom-right
 * corner with a soft shadow + a ring that lifts it off the base (hover lift) — a
 * layered composition, like a photo laid on a photo. Unlike a flat duo side by
 * side: the overlap builds depth and walks the eye from backdrop to detail. The
 * base is held below full width so there is room for the float to overlap inward
 * (it never crosses the section edge). On mobile the float drops to a normal
 * second tile. Text stays --ink (polarity aware); kicker + the em take --accent;
 * images carry --photo-filter; the float ring uses --background so it reads as a
 * cut-out on any theme. Image src are swapped by the photo system. Dedicated to
 * exactly two photos. Part of the `gallery` role.
