// is `{ blocks: ViewBlock[] }` (a spec drawn from the catalog defined in
// internal-packages/dashboard-agent). Here we map each block `type` to its
// component. Unknown types are skipped, so an older/newer agent can never
// render arbitrary content — same guarantee a generative-UI framework gives,
// without the dependency. Add a block by adding a `case` here and a union
// member in the package's `viewBlockSchema`.
