The submarine cable source and the infrastructure data URLs built their asset URLs from import.meta.url while the module loaded. Importing the tool services therefore failed in runtimes without a usable module URL, even for tools that never read those files. Build the URLs when they are read; Vite still rewrites them in browser builds.
