What I'd* like to do is let people upload their own CSS and have HN serve it back to them. Then you can make your own darkmode (or anymode), and people can share them so you can reuse someone else's. One question this is contingent on: does there exist a well-defined secure subset of CSS such that we don't have to worry about weird vulnerabilities? * actually I think this was originally kogir's idea
Custom CSS risks being scope creep, IMO. A dark mode with options of a standard dark and a pure black dark would likely account for 99% of use anyways.

Myself and others with astigmatism literally cannot use "dark mode", tastefully done it's fine tho, talking stuff like Nord theme, monkeytype.com etc as long as it's not straight black and white.
