/**
* Relativize SvelteKit absolute base refs so the build is relocatable under any subpath.
*
* SvelteKit bakes root absolute /_app/ paths into the SPA fallback because paths.relative
* does not apply to a depth agnostic fallback page. Rewriting to ./_app/ lets a plain
* recursive copy of the output into /any/subdir/ resolve assets against the document URL.
* Runs after adapter-static writes index.html and the PWA plugin writes sw.js, deferred the
* same way as buildInfoPlugin so the emitted files exist.
