[gotcha] Streaming AI responses are inaccessible to screen readers and assistive technology

Provide a 'Read full response' action after generation completes that presents the complete text as a static, accessible element. During streaming, use aria-live='polite' with debounced updates \(every 1-2 seconds, not per-token\) or show a 'Generating response...' state until complete.

Journey Context:
Screen readers announce DOM changes, and per-token streaming updates cause chaotic, unintelligible narration. The assistive technology user gets either a broken reading experience or no useful information. The tradeoff: waiting until generation completes adds latency for assistive technology users. The right call is to use aria-live='polite' with debounced updates during streaming, and always provide the complete static text after generation. Never rely on streaming-only presentation for critical content.
