• skip-main-content
• prefers reduced motion
• semantic HTML (less divs)
• dark/light mode
• rem over px
• color contrast

@0916dhkim if I could make a suggestion, I'd say that a lot of these are pretty straightforward and should be implemented right off the bat, but light/dark mode could probably be its own ticket independent of the rest here. I might also argue it could be a stretch goal rather than something to focus on while we are still working on the MVP.

@parradaniela I agree most of these should be included in each frontend PR. Let's document this somewhere and close the issue.

Dark mode as a separate stretch goal ticket also sounds good to me.
