"""Who is calling. The Dodil gateway signs the person in through the app's user pool and passes
them as the X-Dodil-User header (JSON: sub, email, app_roles). It strips any copy a client sends,
so the app trusts it and ships no login code of its own.

Local development: set DEV_USER=you@example.com to act as that person without the gateway.
