- Rename VERTICAL camera mode to FEED (rapid single-item view) - Add SCROLL camera mode with float accumulation for smooth movie-credits style scrolling - Add estimate_block_height() for cheap layout calculation without full rendering - Replace ViewportFilterStage with layout-aware filtering that tracks camera position - Add render caching to FontStage to avoid re-rendering items - Fix CameraStage to use global canvas height for scrolling bounds - Add horizontal padding in Camera.apply() to prevent ghosting - Add get_dimensions() to MultiDisplay for proper viewport sizing - Fix PygameDisplay to auto-detect viewport from window size - Update presets to use scroll camera with appropriate speeds
