Core system:
- AnalyticsUniqId entity (visitor identity with device/os/browser parsing)
- AnalyticsEvent entity (page views linked to visitor)
- POST /t endpoint with AES-256-GCM encrypted payloads
- HMAC-SHA256 visitor hash for anti-tampering
- Async processing via Messenger
- JS module: auto page_view tracking, setAuth for logged users
- Encryption key shared via data-k attribute on body
- setAuth only triggers when cookie consent is accepted
- Clean CSP: remove old tracker domains (Cloudflare, Umami)
100% first-party, no cookies, invisible to adblockers, RGPD-friendly.
