### Email Stack Parity Guard

-   The CLI and `@wraps.dev/pulumi` ship two implementations of the same email stack. A parity test now compares them resource by resource, so a fix landing in one and not the other fails CI instead of drifting quietly
-   Resource names come from shared constants rather than duplicated string literals in each implementation
-   Docs spell out what the library does not provide versus the CLI, and record that Mail Manager ships as a dynamic provider
