The problem
A card that should act like a button is a <div onClick>. No keyboard, no disabled semantics, no role. Copy-pasting those attributes onto every host (button, a, div, Pressable) duplicates bugs.
The pattern that fixes it
useButton / usePress return props: role, tabIndex, onKeyDown (Enter/Space), aria-disabled, press handlers. You spread them onto whatever you render. React Aria is behavior without a DOM opinion. i18n/RTL come from useLocale, not from the component.
