# Multi-stage build for Lux node — installs from published module tags.
# No local source checkout required.

# Build:
#   docker build -f docker/Dockerfile.node \
#     --build-arg NODE_VERSION=v1.23.5 \
#     --build-arg EVM_VERSION=v0.8.35 .
#
# The builder fetches the node binary via `go install` and downloads the
# EVM plugin from GitHub Releases. The runtime image is minimal Debian.
