Simulate an inbound SMS order

Text an order the way a contractor would. Watch the pricing matrix get injected on the turn, and watch the server recompute the total before anything is emitted.

The language parser here is a deterministic stand-in so the demo runs offline. The guardrail is not a stand-in — this page imports evaluateOrder from @vulcan/core, the same module that runs in production, unmodified.
