tourcalc.experiment.docker.from-scratch

# Experimental. Not tested, not even run. Just built
# Self-contained app, with trimming
# Produces ~131M docker image (instead of ~300M when framework-dependent (that is default) and ~187 when no trimming)
# Only linux-arm64 is built-in here (hardcoded in this docker file)
# to build:
#     podman build -f tourcalc.run.docker.from-scratch -t tourcalcdev-s:dev-s --no-cache .
