/**
 * Galleries page — museum wings.
 *
 * Each curated collection is a "wing" of the museum: an italic-serif
 * section title, a piece-count subtitle, a "View the full exhibition"
 * link, and a horizontal row of small framed thumbnails.
 *
 * Frames are thinner than on the pondering page (these are just sample
 * pieces, not the main display) and there are no individual placards —
 * the section header acts as the wing's signage.
