- core/: Pure TS hex engine (axial coords, hex grid, terrain types, edge connectivity with constraint solver, HexMap state model) - src/map/: Leaflet L.CRS.Simple map init, Canvas-based hex overlay layer (L.GridLayer), click/edge interaction detection - src/ui/: Sidebar with toolbar (Select/Paint/Feature modes), terrain picker, hex inspector, map settings (hex size, grid, opacity) - pipeline/: Tile pyramid generator (sharp, from source image) - tests/: 32 passing tests for coords, hex-grid, edge-connectivity - Uses Kiepenkerl tiles (symlinked) for development Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
