Docu. Readability & Add Dark Mode Option

[arxjei]

Hello .. i wanted to suggest a couple of small improvements for the documentation or the theme itself. I think the text could be made a bit more readable. maybe by switching to a more modern and clean font like Poppins. It helps with clarity and makes the messages feel more polished. Also, it would be awesome to have a dark mode option, or even better, default to dark mode since many developers work in dark-themed environments.
