-- [ ] For UI changes, I've tested the changes on different screen sizes (responsive design).
-- [ ] For UI changes, I've checked both light and dark mode.
-- [ ] I've checked the console for any errors that might have been accidentally introduced by my changes.
-- [ ] If important TODOs were left, I've created corresponding issues for them.
