// module (`chomp build:types` from `types/email.d.ts`). This file only
// adds the [`EnvBinding`] trait impl on top of the auto-gen `SendEmail`
// extern type so `Env::send_email("EMAIL")` resolves cleanly.
//
// `EmailMessage` is the constructor class imported from
// `cloudflare:email`, used to build raw-MIME messages and pass to
// `SendEmail.send(message)`. It also doubles as the instance-shape
// type referenced by `ForwardableEmailMessage` and `reply()` — same JS
// object collapsed to a single Rust type, see the d.ts EDIT note for
// the naming rationale.

// doesn't expose a `SendEmail` global for the default

// `wrangler.toml`, the runtime hands us the right shape, so we
