Framer Motion is incompatible with React 19.

Framer itself runs on React 18 and given the scope of breaking changes (subtle and major) I think it is unlikely to be upgraded in the near-term.

To support 19, we preferably have to fix types and animations in a way that is backwards compatible with 18.

Types: #2640
Animations: #2624

Please add further examples of broken behaviour in the comments here.
