Containerfile

# UbiCity container — Deno runtime.
#
# This project is Deno-first (deno.json tasks, Deno.* filesystem APIs,
# jsr:@std/* + npm: deps). The previous Node Containerfile could not run
# it. Pinned to the .tool-versions deno so a plain `git clone` builds an
# image that runs the full test suite and CLI with no host toolchain.
#
#   docker build -t ubicity .
#   docker run --rm ubicity                       # CLI help
#   docker run --rm ubicity deno task stats
#   docker run --rm -v ./data:/app/ubicity-data ubicity deno task report
#   docker run --rm ubicity \
#     deno test --allow-read --allow-write tests/  # full suite (44 tests)
