# Boot-smoke harness: run the backend's OWN image against a throwaway TimescaleDB and
# assert it actually boots + serves its contract (build alone doesn't prove boot). Used
# by scripts/smoke.sh; not a deploy file. DB data is tmpfs (ephemeral) — no volume, no
# residue. See Makefile `smoke` and README.
