[Placeholder — replace with your real privacy policy. At minimum, cover: what data you collect (this build stores no visitor personal data by default — no accounts, no tracking cookies beyond the age-confirmation flag and, for admins, the login session); whether you use any analytics/ads later; how people can contact you with privacy questions; how long the age-confirmation flag lasts (currently: only for the browser session). Have a lawyer in your jurisdiction review this before launch.]
