Welcome to the Registry, Pilot. Here we carve design decisions into JSON, where any tool can read them.
The W3C says a token is an object with a `$value`. Add a `$type` so machines know what kind of thing it is.
Forge me one token at the path `color.brand.primary`. Its $value is `#2dd4ff`. Its $type is `color`.
Mind the spec: dollar-sign keys are reserved. `$value` and `$type` — exactly that.
