/**
 * Variant CSS: gallery--feature-mosaic
 *
 * A mosaic with hierarchy — one large lead image (a 2×2 tile) and five smaller
 * ones in an even square 3×3 grid, with a subtle hover zoom. A magazine rhythm
 * vs the uniform grid or random-height masonry. Robust to count: on mobile the
 * feature reverts to a 1×1 tile so the 2-column grid stays gap-free. Tiles use
 * --decor-radius; images carry --photo-filter.
