Paint it black. It's just a document from the web and now resides on your computer. Do whatever you like with it! There is no authorian sleepy forcing you to consume it like it was.
This does not answer your question. I do not know the answer. That said these [1] are the uBlock Origin rules I use. This includes some colors that can be changed to fit anyone's preference.
I use the third-party app Harmonic to browse HN and it has a dark mode. It's quite nice, actually. Though I do think your tone is unusually inappropriate for a feature request.
I suppose it had to come to light eventually. For many years hundreds of people -- from web designers all the way up to the highest Freemasons -- secretly conspired to thwart every attempt to implement dark mode in HN to frustrate you personally. Not funny indeed.
