// Reference: M13 §2 — SSO Session model
// Tracks a user's SSO session across the system for single sign-on and single logout.
// An SSO session is created when a user authenticates via SAML/OAuth and persists
// until the user explicitly logs out or the session expires.
// This enables: (1) SSO — one login grants access to all accounts for that user,
// (2) SLO — logout terminates all active sessions across all accounts,
// (3) audit — track when/where a user authenticated and from which IdP.
