{# Self-contained "delete my local data" handler for the Datenschutz page. freiedenker.js isn't loaded here, so this is standalone — it builds a RED double-confirm modal from the global .fd-modal / .fd-btn primitives (+ the .fd-modal--danger variant) and, on the second confirm, removes every localStorage key this site owns (the fd-* namespace) and reloads. Wired to any [data-fd-clear-storage] link in the (DB-stored) Datenschutz text. #}
