+Key:
++ Parallelogram: async/await task
++ Box: sync task
++ Diamond: conditional branch
++ Egg: user interaction
++ Blue arrow: async task is allowed to settle but allowed to fail
++ Red arrow: async task success is asserted
+
+Notes:
++ The success of setting up rageshake is never asserted, riot-web has a fallback path for running without IDB (and thus rageshake).
++ Everything is awaited to be settled before the Modernizr check, to allow it to make use of things like i18n if they are successful.
