Resend integration
Use the project's official SDK. Inspect its locked version and types against the current endpoint documentation before coding. Do not add a preview Workflows SDK, a second generic HTTP client, or a frozen OpenAPI copy as the source of truth. Use a supported current SDK for required features; make upgrades deliberate.
