As a user
I want smooth scrolling with large headline datasets
So that FontStage doesn't slow down with 1000+ items

Acceptance Criteria:

  • ViewportFilterStage only processes visible items
  • Camera modes work: vertical, horizontal, omni, floating, trace
  • No performance regression with large datasets (benchmark test)

Technical Tasks (from commits 4c97cfe, 57de835):

  • Implement ViewportFilterStage in engine/pipeline/adapters.py
  • Create engine/camera.py with scroll modes
  • Add test_viewport_filter_performance.py benchmark
  • Add camera tests in test_camera.py
