/**
 * Variant CSS: gallery--lightbox-hint-grid
 *
 * A tidy grid of square frames where every image gets, on hover, a gentle dim
 * plus a magnifier "zoom" icon — a lightbox/preview affordance. Unlike the plain
 * grids and captioned cards: it invites a closer look at each shot. The hint
 * badge sits on an always-dark accent surface, so its glyph safely uses
 * --on-dark / white (KI-020). Image src are swapped by the photo system.
 * Part of the `gallery` role.
