DoveMark carries the dove path from the original home page as its
own component. The hero draws it at the rings' centre, upright while
they turn, with a soft glow and a gentle bob that stops under reduced
motion. The rings' opacity moves from the SVG to their own group so
the dove isn't dimmed with them.
