Summary
What can I say that isn't pretty self-evident from the title?
On Mon 08 Jun 2026, AO3 updated some stuff that broke a lot of things in a lot of people's CSS-works (and at least one userscript). I fixed it. This fix is only client-side, so that you can re-enable some of the magic that some people have wrought and see it once more as a reader — it doesn't act from within a work skin to force a rollback to the actual server-side site-level underlying code itself, so it's not much good directly for authors.
Have you seen some of my CSS demos, or mystyrust's do you believe in coincidences?, or Mewsmodeus (Mewzebub)'s I'M NOT AN FANFIC AUTHOR PLEASE DON'T CURSE ME, or mackerel_cheese's Íkaros in when the wax melts ? If so (before the “update”), then you know and remember; if not, then you're going to want to do so, and you'll want this CSS or JS with which to view them in all of their glory.

Summary
It's bugged me vaguely for years, though never enough that I really cared... but it hit me last night: if JS can do one thing, such as return the special kudos messages to their days of tailored glory, then it can do another, so... yeah, why not?
If you want to see your series' total number of public bookmarks in your stats page: you got it! ❤️
NB: Cf. Userscript to return tailored kudos thanks' and styled comments' visibility client-side re. CSS to return
overflowandsticky, or link for same as a userscript.Full code included.

Summary
Remember when people started tailoring their kudos messages and error notices? Pepperidge Farm remembers — and so do I.
Permit those messages to be seen and go brrrrr again (at least for you as a reader).
I use it in Violentmonkey and Tampermonkey. I don't speak JS (this is me dipping my toes into the water here) and am not at all familiar with the ins and outs of all of the different userscript managers, so you might need slightly different syntax or something if you use a different one (and since I discovered last night that Chrome no longer supports Violentmonkey, and it seems that Tampermonkey and others aren't really open source, I was stuck between Skýlla and Khárybdis). And bonus: it even permits the effect on multichapter works in single-chapter mode!
2x bonus: link at bottom for stats' page SERIES bookmark count.
3x bonus: link beneath that to returnoverflowandsticky.Don't Panic
Make Kudos Great Again!

Summary
A simple workskin and tutorial for including letters in a fic (with a mini fic to demonstrate!).
This workskin merges with the reader's site skin rather than overriding the text or background color (tested with both default/light mode and reversi/dark mode).
