If you want the Talk To Effulgence Characters page to work normally, but other Dreamwidth pages to be use the fullwidth user style, you can use this regex:
That makes the fullwidth style apply to any Dreamwidth page which is not in the Belltower, except for specifically https://belltower.dreamwidth.org/1898.html, because that one is actually part of Effulgence.

Just found this, thank you so much. Going to make reading all the summonthreads so much less annoying.
