shadcn/ui Setup

Sets up shadcn/ui with the modern CSS-first Tailwind v4 setup, not the deprecated v3 approach.

Authorized Scope

Apply this engine only within the user's requested task and existing explicit authorization. Loading or delegating to it grants no additional authority. Preserve report-only restrictions and the caller's target, host, provider, and cost limits. Existing approval satisfies a gate only for the same actions and scope; obtain approval before expanding them. Forward these limits to delegates.

Contract

Inputs:

• Project root directory (defaults to current working directory).
• Optional: theme name (zinc, slate, stone, etc.), component list, router type (app-router or pages-router).
