/*
 * WebCMS content image preview (lightbox) — theme-agnostic styles.
 *
 * This stylesheet is only linked when the operator enabled
 * "content image preview" (SettingContentImagePreview), so every rule here
 * may assume the feature is on. Class names are prefixed to stay clear of
 * the themes' own .aurora-* / .zhuoone-* namespaces and of the removed
 * per-theme lightbox implementation.
 */

/* The script adds this class only while an image is a working preview target,
   keeping the pointer affordance aligned with click and keyboard behaviour. */
