http.FileServer answered /s/ and /s/css/ with an HTML listing of the embedded files, and /s/css with a redirect to that listing. HandleStatic in internal/handlers now looks the name up in the embedded files first and answers 404 when it names a directory; files are served as before. The routes mount it under /s.
