Subject: [PATCH] fix(scroll-area): correct transition-shadows typo so the
 focus ring animates

Tailwind's utility is singular, so `transition-shadows` compiles to nothing: the viewport gets no transition-property or duration and its focus-visible ring snaps in and out. `transition-shadow` sets `transition-property: box-shadow`, which is what `ring-2` and `ring-offset-1` render.

The registry JSON and the packages/ui copy carry the same change.
