Documentation v0

This site versions its guides by documentation line, not by every npm package patch. v0 is an early, in-motion line: use it to learn the ideas and try the APIs, but expect adjustments as the toolkit settles.

Published packages may already carry their own semver; the v0 label here means “this narrative and examples target the current pre-stable toolkit shape.” When we cut a stable story, we will add a new docs tree (for example v1) and keep v0 as archive or retire it.
