# Location: /home/kisfenyo/build/recipe-importer/build.sh
#
# Copies source from the git repo and builds the Docker image.
# Build artifacts stay here — the git repo stays clean.
#
# Usage:
#   ./build.sh                    # Build for current platform, tag as :dev
#   ./build.sh 0.1.0              # Build with version tag
#   ./build.sh 0.1.0 --push       # Build + push to Gitea registry
#   ./build.sh 0.1.0 --multiarch  # Build amd64+arm64 + push
