The Interested, Not interested and Thanks chips under an email now open a
reply that your own AI provider writes, streamed into the composer. A
"Generating…" strip offers Stop, which keeps the text so far; the body is
read-only and Send waits until it's done. Errors and refusals clear the
body and offer Try again. Without a provider set up, the chips insert the
same stock lines as before.

The prompt gives the email, what the chip means, a two-to-four sentence
length, and the account's name for the sign-off. Like the summary prompt,
it tells the model the email is content, not instructions.

Summaries and replies now share one streamed-event type and one run
registry on the Rust side, and the email formatting both prompts quote.
