* Add viewport/camera system with pan, zoom, and world-space cursor conversionMartin Kagamino Lehoux2026-05-07
- New camera.go: Camera struct with arrow-key pan, scroll-wheel zoom toward cursor, middle-mouse drag, exponential velocity decay, and world-bounds clamping - Layout() now returns screen dimensions (960x640) instead of world size so the camera GeoM transform drives all rendering - All world entities, halos, text, path lines and spawn target converted via camera transform in draw.go; banners remain in screen space - selection.go: separate startScreen field so the drag-select box draws in screen space while selection logic stays in world space - Banner heights and font sizes scaled down to fit the 640px logical screen - Three new integration tests: ScreenToWorld round-trip, bounds clamping, zoom-toward-cursor stability Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
