The list script matched the whole forum, thread pages included, and injected its
stylesheet there before bailing out of its own build. Both stylesheets were
therefore live on every thread, and rules sharing a class name resolved by
userscript load order rather than by intent — a layout that could differ between
two machines with the same files installed. One of those clashes was already
costing the clearance behind the fixed bar.
A single script picks its view from the page type instead, which turns the
shared class namespace from a hazard into a plain fact of the file, resolved
with a modifier on the root element. Pages outside either view now stay
untouched, where before they still received a full stylesheet.
Two things the merge brought to light: the global image rule was overriding the
avatar dimensions, which only went unnoticed because square avatars happen to
scale to the same result, and a zero-width space had been sitting in the source
as a literal character rather than an escape.
Installations carrying the old thread script have to remove it; the remaining
one keeps its name and updates in place.

The project instructions describe testing against a saved forum page without
mentioning that the ignore rules exclude it. A fresh clone therefore has no
fixture, and obtaining one requires a logged-in session — not something that
becomes apparent from a missing file alone.

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.
