How it's built
295-line Python service using stdlib only — no pip installs, no third-party dependencies. Runs as a systemd service on my AlmaLinux VPS behind an OpenLiteSpeed proxy. The whole thing was intentional: if I'm going to give away an SEO tool, I'm not going to build something that breaks the moment a dependency goes out of date.
