/*
 * Shared popup-dialog multi-select filter component, used by every archive
 * that renders a filter through bgm_theme_render_filter_popup() (currently
 * /yerler/ and /rotalar/). One interaction pattern, one set of rules — each
 * page only themes the accent colour via --bgm-filter-accent /
 * --bgm-filter-accent-soft (defaulting to the site's navy primary), scoped
 * on that page's own filter container. See [[bgm_yerler_filter_popup_pattern]]
 * in project memory for how this got extracted.
