QA: A2UI Fixed Schema — Mastra

Test Steps

• Navigate to /demos/a2ui-fixed-schema
• Verify the CopilotChat surface renders with "Find SFO → JFK" suggestion
• Click the suggestion; verify the agent calls generate_a2ui and a flight Card renders with:
  • Title "Flight found"
  • Airport codes SFO → JFK (with Arrow component between)
  • AirlineBadge pill showing "UNITED"
  • PriceTag showing "$289"
  • A "Book flight" button (stateful — becomes "Booked ✓" after click)

Expected Results

• Fixed-schema catalog: Title, Airport, Arrow, AirlineBadge, PriceTag, and a stateful Button override
• Clicking the button transitions to the Booked ✓ confirmation state without a round-trip to the agent
