"""
Auth API — generic endpoints for linking Discord users to external services.
GET /api/v1/auth/login?service=X&token=Y&discord_id=Z
Validates the link token and serves a service-specific login form.
POST /api/v1/auth/login
Accepts the form submission, validates credentials against the service,
stores the session, and returns a result page.
GET /api/v1/auth/status?discord_id=Z
Returns which services are linked for this Discord user.
