Create a clean technical architecture illustration for Lucky running in Docker. Show an external IPv4/IPv6 client reaching a Linux host, the Lucky container using host networking, and Lucky routing traffic to an internal IPv4 service. Include separate labeled flows for reverse proxy, DDNS updates to a DNS provider, ACME certificate issuance, and WOL packets. Show the host directory mounted to /app/conf as persistent configuration. Use a restrained blue and teal palette, simple network icons, Chinese labels, no product screenshots, no credentials, no real IP addresses, no logos, and no decorative text. The image is explanatory only; do not imply runtime measurements.
