New standalone debug prototype exploring the "gem-cut" flying island
shape: a flat hexagonal table (center region) surrounded by 6 sloped
trapezoidal facets down to the girdle (6 outer regions), with a
non-walkable 6-sided pavilion pyramid below for the underside. Crown
gets trimesh collision for later player testing; all 6 outer facets
stay visually neutral (alternating flat color only) since theming
comes later. Doesn't touch main.tscn or the old cross-layout prototype.
Godot 4.6 exploration game with player movement, step-rotation camera
rig, and POI interaction system (explore/rest/close menu). main.tscn
is a test scene with placeholder props; debug/ holds unwired terrain
prototypes (voxel river, procedural island mesh, cross-shaped hub
