/**
 * HCTCLIENT01 Album Content Block V1
 * ----------------------------------
 * Theme customization boundary:
 * - Masonry columns, gap, radius, caption and hover styling live here.
 * - Lightbox behavior lives in js/blocks/hctclient01-album-lightbox.js.
 * - Shared backdrop color/blur stays in hctclient01-ui-core.css so mobile menu,
 *   modal and lightbox always use one visual layer.
 *
 * Required responsive contract:
 * - Desktop: 3 masonry columns.
 * - Tablet: 2 masonry columns.
 * - Mobile: 2 masonry columns.
 *
 * A future theme can override these custom properties without changing Blade/JS.
