/* NoliDrop public mini-site — static, no trackers, no external requests.
   Four languages (FR / EN / ES / IT) via a pure-CSS toggle (hidden radio
   buttons), so the site works with JavaScript fully disabled. A tiny i18n.js
   layers on top: it reads ?lang=fr/en/es/it (and localStorage) to preselect the
   language, keeps it across pages, and syncs the URL / <html lang>. */
