/**
 * Variant CSS: gallery--framed-quad-captions
 *
 * Four frames in a 2×2 grid, each set in a thin passe-partout mat with a caption
 * below (project title + an auto 01–04 index from a CSS counter). Unlike the bare
 * square quad or the filmstrip: every photo gets its own "gallery label", like
 * works hung at an exhibition. Text stays --ink (polarity aware); kicker, the em
 * and the index take --accent; the mat uses --surface + --decor-radius; images
 * carry --photo-filter. Image src are swapped by the photo system. Dedicated to
 * exactly four photos. Part of the `gallery` role.
