                -Remove hard-coded routes for files in the application's "root"
                (`static/`) directory; redefined Flask's `static_url_path`
                accordingly. Files can now be directly accessed by URL.

Add:
        static/img/favicon.ico

        static/(robots.txt, sitemap.xml)
                -Add search-engine files. `bitshift` is not yet registered with
                Google.
