/* DropFormat floating feedback widget.
 *
 * Re-uses the theme tokens defined in converter.css (--df-bg,
 * --df-accent, etc.) so the widget inherits light/dark switching
 * automatically without its own token table. The widget mounts on
 * any page served by the landing template (home, privacy, terms,
 * and every converter page), so it stays visually adjacent to the
 * site chrome without being part of it.
