So, we load all the CSS and all the HTML templates here in the head. Are there performance concerns with doing this? I mean, I know we're not fetching from a remote server, but we're still queueing up a bunch of disk IO to fetch these.

Or maybe it's the case that this module will be initialized at phone startup time, so that the user is better off with a marginally slower startup, instead of lazy-loading html as the user is actually interacting with the fxa app?
