# Non-secret oauth2-proxy configuration (client_id/secret/cookie_secret come from
# the oauth-credentials Secret). oauth2-proxy is the single auth front for the
# arrstack: it authenticates the UI and the token API against Authentik, and path-
# routes to the arrproxy-ui / arrproxy-api upstreams. /<app>/api is exempted from
# auth (SKIP_AUTH_REGEX) so *arr clients presenting a per-user token reach the api
# directly; the api then validates the token. Everything else requires the oauth
# session and receives identity via X-Forwarded-* / X-Auth-Request-* headers.
