Aimed at developers shipping small applications to a single internet-facing host rather than to a managed PaaS. Currently focused on Flask behind Caddy; will expand with other stacks as they earn their own walk-throughs. Read this after host-hardening and edge-hardening — the deployment recipes assume the box and the edge are already configured to a defensible baseline.
After this series: your Flask app runs as a systemd-hardened service behind Caddy’s auto-TLS, with the deployment integration bumps you’d hit on your own already documented and worked around.
