# Manual multi-arch build + push fallback when Gitea Actions isn't available.
#
# One-time setup:
#   docker buildx create --name multi --use
#   docker run --privileged --rm tonistiigi/binfmt --install all
#
# Auth:
#   docker login rg.nl-ams.scw.cloud -u nologin -p <SCW_SECRET_KEY>
#
# Usage:
#   ./build.sh
#
# Always tags:
#   :latest                — moving pointer
#   :<git-short-sha>       — immutable, traceable to a commit
#   :<pyproject-version>   — semver from pyproject.toml (e.g. :0.1.0)
