# Docker entrypoint for shakemap4-web.
#
# Runs all optional setup steps before handing control to nginx:
#   1. Cron scheduling for periodic event processing (ENABLE_CRONTAB)
#   2. One-shot full data processing at first boot (PROCESS_ALL_DATA_FIRST_TIME)
#   3. Environment profile selection via SHAKEMAP_ENV
#
# Every step is opt-in: with no env vars set, the container just serves the
# static site with INGV defaults from config-base.js.
