- Creates dimensional network visualization with arrows connecting nodes
- Animates through effects and highlights active camera mode
- Add --pipeline-diagram flag to generate mermaid diagrams
- Create engine/pipeline.py with PipelineIntrospector
- Outputs flowchart, sequence diagram, and camera state diagram
- Run with: python mainline.py --pipeline-diagram

- Add --demo flag that runs effect showcase with pygame display
- Add HUD effect plugin (effects_plugins/hud.py) that displays:
- FPS and frame time
- Current effect name with intensity bar
- Pipeline order
- Demo mode cycles through noise, fade, glitch, firehose effects
- Ramps intensity 0→1→0 over 5 seconds per effect
