feat: improve mobile support

remove mobile-specific font size i’ve noticed native ios apps actually tend to use a smaller font size by default anyway

also maybe increase button touch targets, and figure out a way to dynamically add some margin to the bottom of the screen on mobile so that you can reach the action buttons better on phones like iphone X

also i need to test and improve on android aswell, i just dont have an android device so i may need to borrow one or emulate one
