[gotcha] User retries a slow AI prompt causing duplicate token charges and interleaved streaming chaos

Disable the submit/send button and input field while the AI is streaming. If a cancellation is allowed, use an AbortController to kill the HTTP request on the client and, if possible, cancel the upstream API stream, rather than blindly sending a new request.

Journey Context:
Standard web UX says 'let the user retry if it's slow.' But AI APIs are stateless and charge per token. A retry doesn't cancel the first request; it just adds a second one. The UI then receives two competing streams interleaved, corrupting the state, and the backend bill doubles. The tradeoff is user control vs. cost/state consistency. You must treat AI generation as a blocking transaction in the UI, not a standard idempotent REST call.
