Create and publish an invitation or letter.

}🟢get_letter(id, editKey)
Read a letter you created (needs its editKey): its content, links, images, and the guests' RSVP answers (yes / maybe / no, plus who hasn't answered).

}🟡update_letter(id, editKey)
Change a letter. Only the fields you send change (lang, style… are kept). Links keep working. You may send the same object get_letter returned, including its card wrapper — it is applied. A body with no letter fields is an error, not a silent success. `guests` replaces the list but keeps each existing guest's id and link (matched by id, then by name); `addGuests` appends without touching anyone else. Image URLs are copied at full size. Text has no character limit; italic: true (or fontStyle: "italic"); custom.frame is none | rule | ornate.

}🔴delete_letter(id, editKey)
Delete a letter for good (needs its editKey): its links stop working, and guest names, RSVP answers and images are erased.
