"""Session bootstrap: the one endpoint reachable without a session (US07-02).
It sets the ``HttpOnly``/``SameSite=Strict`` session cookie and returns the CSRF
token in the body. A foreign page can call this — it just cannot read the answer,
because the app sends no CORS headers — and the cookie it received is never attached
to a request that foreign page initiates.
