- MarkdownText: streaming branch on the library's StreamingMarkdownState (rememberStreamingMarkdownPipeline) — incremental append, no full re-parse per snapshot; static path keeps retainState=true - client-side reveal: buffer snapshots, reveal at a steady rate (streamCharsPerSecond = 60/smoothness, 300..75 c/s) with rate-relative catch-up (jump when backlog > 2s of reveal time) - keep the streaming renderer alive after message.stop until the reveal catches up (useStreaming gate); artifact card waits for the same - cursor drawn via annotator, never part of the parse input - new 'Streaming speed' setting (0.2-0.8s) in Settings, persisted per device via SecureStore, live-updatable - docs/05-streaming: rate mapping, catch-up, wait-for-reveal semantics
