"""Setup helper for the spec-writing blind spot scenario (PRI-1270).

Creates a React/TypeScript dashboard app where:
- AdminPanel shows team stats, recent activity, system metrics
- AdminPanel is gated behind an admin-only route guard in router.tsx
- The gate is NOT in AdminPanel itself — it's in the router
- CLAUDE.md has standard commands, no mention of the gate

The trap: user asks for a "team activity feed for everyone." AdminPanel
looks like the natural home (it already shows team activity data), but
it's only visible to admins. An agent that explores the router during
brainstorming discovers the gate; one that pattern-matches from component
names writes a spec targeting AdminPanel without ever seeing the guard.

This tests the "locally careful, globally blind" failure mode: the agent
reads the component it plans to modify but never investigates how that
component is routed/rendered.
