# Runtime image only — the Spring Boot executable JAR must be built *before* `docker build`.
#
# Typical flow (GitHub Actions or locally):
#   1. cd ui && npm ci && npm run build
#   2. mvn -pl standalone -am package -DskipTests
#   3. docker build -t spec0/mock-server:latest .
#
# REST E2E (build image, run container, hit APIs): ./scripts/e2e-against-docker.sh
#
# Build context: the `mock-server/` directory.
