Poem

A rabbit hops through workspace rows,
Mermaid’s bright logo softly glows.
A link, a badge, a name in flight,
Three tidy records set right.
“Hop approved!” says the rabbit tonight.

Learning: When documenting pnpm peer dependency resolution, accurately explain that pnpm can treat a package listed only in peerDependenciesMeta as an optional peer, even without a matching peerDependencies entry. Verify examples such as debug and distinguish this behavior from the conventional peerDependencies-plus-peerDependenciesMeta declaration.
