# Stage 1: Builder - compile FIPS OpenSSL (dual-version approach) and install dependencies
# NOTE: Builder uses Debian (not Alpine) because the distroless runtime is Debian-based (glibc).
# Alpine uses musl libc which produces incompatible binaries for the distroless glibc runtime.
# The OpenSSL build pattern follows DockerfileAlpine's dual-version FIPS approach.
