Guide to the Kumo UI CLI (npx @cloudflare/kumo) — listing components, querying component docs and props from the terminal, and scaffolding customizable "Blocks" into a project's source directory. Use whenever the user is setting up Kumo UI in a React project, asks how to install or run the Kumo CLI, wants to add a Block like PageHeader or DeleteResource, needs Kumo's semantic color token / Tailwind v4 / ESM conventions, or mentions "npx @cloudflare/kumo" by name.
