Web applications that lose authentication state on network drops force users to re-authenticate. Tokens stored in plaintext are accessible to any script running on the page.
"Offline-capable. Auth tokens encrypted. Auto-refreshed."
The editor shell stays functional and authenticated even when the network drops. Auth tokens are AES-GCM encrypted, requests are HMAC-signed, and tokens refresh automatically without user action. Caching, offline support, and dynamic CSS imports all managed through the Service Worker layer.
- AES-GCM encrypted auth. Tokens stored with hardware-backed encryption, not plaintext.
- HMAC-signed requests. Every request to backend Workers is cryptographically signed.
- Auto token refresh. Tokens refresh automatically without user interaction.
- Offline support. The editor shell works without a network connection.
