/**
 * ACB Product Gallery
 * Layout consumes CSS custom properties; the Elementor style controls set those
 * properties per instance (and responsively), so this file stays the single
 * source of truth for structure. Values below are the out-of-the-box defaults.
 *
 * Selectors are scoped under .acb-gallery (and a few use !important on resets)
 * specifically so theme / Elementor global *button* and *list* styling can't
 * leak into the thumbnail and navigation elements (that leak is what caused the
 * gold borders and the off-centre thumbnail row).
