UI Runtime

nyatikit provides the shared UI runtime surface.

Contract

• runtime events are projected into UI events
• UI timelines receive typed stream updates
• message, status, progress, and tool rows remain distinct
• products own layout and workflow, not the transcript protocol

Preferred flow

initial page load
  -> rendered shell and initial snapshot
normal interaction
  -> small mutation or stream event
  -> local reactive state update
LLM turn
  -> UI stream event
  -> keyed timeline update

This avoids the failure mode where a product repeatedly fetches and replaces large HTML regions instead of updating the affected timeline state.
