Each client app sets a persistent first-party device cookie ({app}_did).
On each request:
- Logged in: verify grant via account internal endpoint (cached 60s)
- Not logged in + device cookie: check-device endpoint detects if user
logged in since last grant revocation → triggers OAuth automatically
No cross-domain cookies. No propagation chain. Each app checks independently.
