Sent through Cloudflare Email Service with the send_email binding EMAIL — the same channel nemo12 uses; no API key exists to leak.

• Templates in 6 languages: workers/api/src/modules/email/templates.ts (tested: every language mentions the order code and tracking link).
• Sender: MAIL_FROM = ArtLove365 <orders@artlove365.com>; studio copy: STUDIO_EMAIL.
• Sending never fails an order: results are logged as sent, skipped (binding missing) or failed (e.g. E_SENDER_NOT_VERIFIED until OPS-02 is done).
