The tokens assigned to an area, and what each is assigned.
Every token is optional, so an override names the ones it restyles and leaves the rest at whatever the cascade
already gives them. Each takes the value that token admits, be that a name off the ladder it belongs
to or a CSS value of the shape it carries, so an editor offers the handful of names and keywords that belong where
one is assigned: a colour offers colours, a text size the type and scaling ladders, the visual register the three
words it is defined over.
