Yeah, it's not impossible to get good speed on dark mode; my parent suggested that reader doesn't work well if you have a ton of JS/CSS and I replied that I do not have JS and not-quite-a-lot of CSS for reasons, so reader works fine for people who want to read my site. Your site is very minimalistic, and that is fine, because it's your site and it's what you like and it's your hobby. I'm less of a minimalistic person, so dark mode would require thought on how I would present a dark theme to users other than just coloring black and grey or white. That's too much work for me and it's personally not interesting (mostly because I do not like dark themes).
