The map controller takes a point as [lat, lng, href, title] and a place
as [id, href, title]. A pin with an href is clickable, names its title
on hover and is followed through Turbo; an area filled on a boundary
layer is followed the same way. A bare point or place still draws a pin
that leads nowhere.
