Applications should have an associated cron job

To overcome occasional failures without requiring manual attention it would be good to establish a cron job, run every 20 minutes, that will restart the server if it is no longer running.

Start by reviewing the repository's deployment and ancillary logic for WebFaction and determine how the Flask server is currently launched. Define the cron entry and restart behavior for a stopped server, then verify that the job runs every 20 minutes and restores the application without manual intervention.
