10	* AI generator for one email-template's subject + body.
11	*
12	* The caller (EmailTemplateForm) opens this with the template's
13	* catalog metadata pre-filled — template_key, name, description,
14	* recipient_type, merge_tags. The operator picks a tone, optionally
15	* adds extra context, hits Generate. The backend agent emits one
16	* `set_email(subject, body)` tool call so the response shape is
17	* guaranteed structured (no regex parsing).
18	*
19	* On accept, the modal calls `onAccept({subject, body})` and the
20	* form replaces its current values with the AI output. On cancel,
21	* the existing subject/body stay untouched — the operator can try
22	* again without losing what they had.
