Convert the existing Preact components into Vue components. Biggest effort here: Coordinating the state and transitions of 3 banners in one: Mini banner, Followup banner, and Soft-Close banner
- Mobile DE banner is ported to Vue
- figuring out the modal display (also scroll behaviour)
- use of funds
- use of funds button (Donate Now) does not lead to /
- The expanded/follow-up/main banner can be changed to a modal.
