/* image-field.css
 * Styles for the shared image-field widget (assets/js/shared/image-field/).
 * Mounted by the Spell Creator, the Campaign Forge entity panel, and the
 * Monster Creator. Colors come from the shared theme tokens defined in
 * assets/css/main_style.css (--primary-color, --card-bg, --text-*, etc.) with
 * fallbacks, so the widget inherits each host's accent without hardcoding.
