"""Build the Spotlight or a single promoted link.
The frontpage gets a Spotlight box that contains promoted and organic
links from the user's subscribed subreddits and promoted links targeted
to the frontpage. Other subreddits get a single promoted link. In either
case if the user has disabled ads promoted links will not be shown.
The content of the Spotlight box is a bit tricky because a single
version of the frontpage is cached and displayed to all logged out
users. Because of the caching we must include many promoted links and
select one to display on the client side. Otherwise, each logged out
user would see the same promoted link and we would not get the desired
distribution of promoted link views. Most of the promoted links are
included as stubs to reduce the size of the page. When a promoted link
stub is selected by the lottery the full link is fetched and displayed.
There are only ~1000 cache resets per day so it is necessary to use
a large subset of the eligible promoted links when choosing stubs for
the Spotlight box. Using 100 stubs works great when there are fewer than
100 possible promoted links and allows room for growth.
