# Matrix Authentication Service (MAS), Element's OIDC provider. QR code device
# linking (MSC4108) needs it: Synapse refuses msc4108_enabled without delegated
# auth, and /_matrix/client/v1/auth_metadata exists only with it. MAS starts only
# when AUTH_ENABLED=true; otherwise the binary (~50 MB) sits unused and the
# rendered Synapse config is unchanged.
#
# The upstream image is distroless, with the binary at /usr/local/bin/mas-cli and
# its templates, translations, assets and policy.wasm under /usr/local/share/mas-cli.
# Its distroless/cc-debian13 base shares the glibc generation of our
# python:*-slim-trixie base, which the ldd check below proves per architecture.
