NEW web design with better contrast incoming! :D Thank you for the feedback :)
Your dark mode choice for your late night chat is appropriate, and good branding. If someone’s technically literate enough to engage with an SSH-based social network, then they should be capable of injecting user scripts, custom CSS, and/or deploying assistive browser extensions, OS settings, and screen readers.
If this were a website about cataract treatments or a Metamucil landing page, then it would be a bad design.
