  "description": "Share one Internet Identity sign-in across sibling subdomains, so signing in on one app signs the user in on the others without a second visit to II, and signing out on one signs them out everywhere. Covers the shared record with CookieStateStorage, the /reauth route that silently acquires each app's own credential under transport: 'redirect' and prompt: 'none', the per-origin /.well-known/ii-auth-callbacks document, reading signed-in-elsewhere on load and offering it mid-session, and what ends a shared session. Use when two or more apps under one domain must share one signed-in user, when moving between them asks the user to sign in again, or when /reauth bounces in a loop. Every app must already derive from one elected primary origin: load internet-identity and settle that first. Do NOT use for a single app on one origin, which needs none of this, or for apps on unrelated domains, which cannot share a cookie.",
