This page is optimized for perceived performance. Our enemies are the time
taken for the backend to generate our data, and the time taken to parse
and render the starting HTML/CSS content of the page. This page is
designed to let Chrome do both of those things in parallel.
1. Defines temporary content callback functions
2. Fires off requests for content (these can come back 20-150ms later)
3. Defines basic functions (handlers)
4. Renders a fast-parse hard-coded version of itself (this can take 20-50ms)
5. Defines the full content-rendering functions
If the requests for content come back before the content-rendering functions
are defined, the data is held until those functions are defined.
