Split monolithic scroll.py into focused modules: - viewport.py: terminal size (tw/th), ANSI positioning helpers - frame.py: FrameTimer class, scroll step calculation - layers.py: message overlay, ticker zone, firehose rendering - scroll.py: simplified orchestrator, imports from new modules Add stream controller and event types for future event-driven architecture: - controller.py: StreamController for source initialization and stream lifecycle - events.py: EventType enum and event dataclasses (HeadlineEvent, FrameTickEvent, etc.) Added tests for new modules: - test_viewport.py: 8 tests for viewport utilities - test_frame.py: 10 tests for frame timing - test_layers.py: 13 tests for layer compositing - test_events.py: 11 tests for event types - test_controller.py: 6 tests for stream controller This enables: - Testable chunks with clear responsibilities - Reusable viewport utilities across modules - Better separation of concerns in render pipeline - Foundation for future event-driven architecture Also includes Phase 1 documentation updates in code comments.
