/*
 * galleries-city.css  — delta stylesheet for SSR galleries listing pages
 *
 * Loaded AFTER https://www.zopart.com/styles.css (provides Google Fonts,
 * CSS variables, base typography) and site-chrome.css (header/footer).
 *
 * Shared patterns reused from exhibitions-city.css:
 *   body flex-column, .page-main, .page-inner, .page-heading, .page-title,
 *   .page-subtitle, .city-nav + .city-nav__item[--active], .status-nav +
 *   .status-nav__item[--active], .empty-state, .empty-state__signin-btn,
 *   .hidden utility.
 *
 * New classes introduced here (gc-* prefix):
 *   .gc-breadcrumbs, .gc-breadcrumbs__sep
 *   .gc-district-filter, .gc-district-chip, .gc-district-chip--active
 *   .gc-gallery-section, .gc-gallery-grid
 *   .gc-card, .gc-card__image-container, .gc-card__image-link,
 *   .gc-card__image-wrap, .gc-card__image, .gc-card__image-placeholder,
 *   .gc-card__save, .gc-card__body, .gc-card__name, .gc-card__name-link,
 *   .gc-card__address
 *
 * Classes shared with exhibitions-city.css (candidate for promotion to
 * a shared site-cards.css in the cards-consistency phase):
 *   .city-nav, .city-nav__item, .city-nav__item--active
 *   .status-nav, .status-nav__item, .status-nav__item--active
 *   .empty-state, .empty-state__signin-btn
 *   .page-main, .page-inner, .page-heading, .page-title
 *   The save-button visual treatment (position:absolute top-right, white icon)
