Caddy is a web server and reverse proxy that automatically handles HTTPS via Let's Encrypt. It terminates TLS for all folk.zone services and routes traffic to the appropriate Docker containers.
Caddy is configured via Caddyfile in the server directory. It automatically obtains and renews SSL certificates for all folk.zone subdomains.
