Feature Implementation On‑arrival selfie Silently captures a front‑camera photo, uploads to /ID/, and stores the path in visitor_logs. Footprint logging Logs IP, User‑Agent, screen size, timezone, battery, network info, and all permission states to visitor_logs. Permissions Requests camera+mic (one prompt), geolocation, and notifications on page load. LIFE button Opens the camera modal with photo/video recording, rotate, and location‑aware uploads. Works because mic permission is already granted. FOTO button Silently captures a photo using the back camera (or fallback) and posts it immediately. Page layout Content grid, search, filter, pagination, map – completely unchanged.
