# Mock LiveKit API server for SDK conformance testing. Build from the repo
# root:  docker build -f cmd/test-server/Dockerfile -t livekit/test-server .

# Pinned by digest so the build is reproducible even if the tag is republished.
# The tag is kept alongside it for readability; Renovate updates both together.
# --platform=$BUILDPLATFORM runs the builder natively and cross-compiles via
# GOARCH below, rather than compiling under QEMU; see the repo-root Dockerfile.
