Several traits of this codebase cost time to rediscover and are invisible in
the source: both scripts share a stylesheet namespace on thread pages, the page
indicator in the forum markup is split across inline tags so searching the raw
HTML for it comes up empty, and anything appended to the body has to come after
the original content is hidden.
The file also records the throwaway jsdom harness used to check the thread
script against a saved page, since the project deliberately carries no test
dependencies and the setup is easy to get wrong.
