Dockerfile

# Multi-stage build using openenv-base
#
# This Dockerfile is flexible and works for both:
# - In-repo environments (with local src/core)
# - Standalone environments (with openenv-core from pip)
#
# The build script (openenv build) handles context detection and sets appropriate build args.
