I still donโt know what the best approach is regarding user friendliness. But personally I think all web pages should follow the system color, and the browser should provide a way to override it in case you do need it (I think @zen-browser.app allows this)
i can only read @leaflet.pub posts during the day because their bright whiteness jumpscares me at night, so i've learned not to click (thanks embeds!) is that a setting people aren't using, or lack of support for system color scheme?
