Debug & Deploy Base44 Site

My marketing site still relies on an old Base44-centric codebase and the build keeps failing because of those legacy dependencies. I need you to step in, track down whatever is preventing a clean build, and trim away the Base44-only parts so the project can compile and run without them...
