/**
 * Email Send-With-Template API Route Handler for Next.js
 *
 * Sends an email rendered from a named template.
 * Re-export in your Next.js application at /api/email/send-with-template.
 *
 * @example
 * ```typescript
 * // app/api/email/send-with-template/route.ts
 * export { POST } from 'nextly/api/email-send-template';
 * ```
 *
 * The service returns `{ success, messageId? }`; the body surfaces both
 * fields plus the resolved template id alongside a server-authored toast
 * via `respondAction`. The attachment resolver throws `NextlyError`
 * directly (validation for caller-fixable failures, internal for storage
 * I/O); the machine-readable `EMAIL_ATTACHMENT_*` code lives at
 * `error.data.errors[0].code`.
 *
 * @module api/email-send-template
