/**
 * Unify Opt-in — front-end popup.
 *
 * Themed by two custom properties the plugin injects inline from the settings:
 *   --uo-accent  (button + focus ring)
 *   --uo-radius  (panel + control corners)
 * Everything else is neutral so the popup sits comfortably on any client site.
 * All selectors are namespaced under .unify-optin to avoid collisions.
