+The `package.json` pulls `@x402/core`, `@x402/evm` (`^2.11.0`),
+`@x402/express`, `@x402/fetch`, `@anthropic-ai/sdk`, `express`, `viem`,
+and `dotenv`. Canonical `@x402/evm 2.11.0+` ships with built-in Mezo
+support and the dynamic-price `DynamicPrice` hooks this demo uses, so
+MUSD formatting, Mezo-specific constants, and per-request pricing
+resolve correctly with no overrides. `@x402/core`, `@x402/express`,
+and `@x402/fetch` are the same packages on every chain; Mezo support
+comes in through the `@x402/evm` scheme plugin you register at runtime.
+
+If `pnpm install` resolved `@x402/evm` to a `2.10.x` version through a
+transitive dependency, apply the `^2.11.0` pin from
+[Quickstart Step 6](./x402-quickstart/#step-6-apply-library-overrides)
+before continuing.
