REM  This script:
REM    1. Asks the user for the values that differ per-host
REM       (sa password, port, data dir, container name, edition)
REM    2. Writes a .env file that docker compose will read
REM    3. Downloads Dockerfile + docker-compose.yaml from Hugging Face
REM    4. Downloads the 4-part 7z archive (~40 GB total) from HF
REM    5. Extracts sec_fsnds.mdf + sec_fsnds_log.ldf into the data dir
REM
REM  Requires: curl (built in on Windows 10 1803+), Docker Desktop,
REM            and 7-Zip (7z.exe) on PATH or at the default install path
