Optimizing the gathering of that small bit of data hasn't happened yet, 
and it will.

The point for now is making sure the front end does the right things 
with the data once it has it.

At the moment, it's still being pulled from the database the same way 
the current page does -- all at once before any rendering, on the fly, 
with little caching. That's not our target. The page is built 
anticipating we'll change this to fetching the data in pieces (a few API 
points need to be built), and we'll definitely make use of better 
caching of those pieces.
