The BBC's open source engineering site covers web tools, accessibility, responsive testing and data journalism graphics.
Commenters link it for tools like Wraith and Gel and for BBC accessibility and testing guidance, and recall the old Betsie text tool.
I haven't been able to find anything specifically around popup animations, but the BBC's Cape initiative discusses some of the stimulations etc. that can be intrusive for those with neurodivergent conditions such as autism spectrum condition, ADHD, etc.
I've found that most of these chatbots will use sound alerts to draw attention, and Cape's environmental toolkit definitely references these. While a lot of the content in this toolkit is for physical environments, a lot of it will transfer to digital product UX in terms of stimuli etc.

- Every Layout: https://every-layout.dev Explains the whys and the hows.
- Inclusive Components: https://inclusive-components.design (one of the co-authors of Every Layout). Explains the whys and the hows of building proper components
Additionaly:
- BBC Gel: https://bbc.github.io/gel/ (one of the co-authors of Every Layout) also explains a lot of the whys in design of specific components
- Gov.uk is also great: https://design-system.service.gov.uk/get-started/
The BBC has guides for using the common tools:
https://bbc.github.io/accessibility-news-and-you/accessibility-and-testing-with-assistive-technology.html
Microsoft has documentation on the built-in Narrator: https://support.microsoft.com/en-us/help/17173/windows-10-hear-text-read-aloud
Apple has docs about VoiceOver on iOS and macOS: https://help.apple.com/voiceover/info/guide/
- https://design-system.service.gov.uk/
- https://bbc.github.io/gel/
- (not strictly design system s) https://every-layout.dev/ and https://book.inclusive-components.design/
These are by people whose primary goal isn't promotions, keynotes or CVs.
Tailwind also does a decent job with both the framework itself and the commercial UI examples: https://tailwindui.com/
Great flashback. I used Betsie on several projects in the early 2000s.
It was quite useful when you were stuck with baroque HTML generation code you were unable to modify.
The BBC produce a bunch of interesting tools for web development, another being the layout comparison tool, Wraith:
https://bbc.github.io/wraith/
We do actually have automated testing tools for that. https://bbc.github.io/wraith/ is one: see the write-up https://responsivenews.co.uk/post/56884056177/wraith or a contemporary interview https://source.opennews.org/articles/responsive-css-testing-made-simple-bbcs-wraith/ .
I get your overall point, though.
