函数
void	eve::grid::cellToWorld (const GridConfig &cfg, int cx, int cy, float &px, float &py)
	Maps a cell to planar coordinates (px, py). On XY plane these are world (x, y); on XZ plane they are world (x, z).
float	eve::grid::cellToDepthY (const GridConfig &cfg, int cx, int cy)
	2D sort key (cell foot Y), matching map::tileToDepthY semantics. Unused on the XZ plane.
void	eve::grid::worldToCell (const GridConfig &cfg, float px, float py, int &cx, int &cy, int mapW=1, int mapH=1)
	Maps planar coordinates to the nearest cell. Staggered/hex layouts use a bounded nearest-neighbor search; mapW/mapH bound the search range (Tiled-compatible pick semantics).
void	eve::grid::foreachRotatedFootprint (int w, int h, const std::vector< uint8_t > &mask, int steps, bool hexMode, const std::function< void(int lx, int ly)> &fn)
	Enumerates local cells of a rotated footprint.
void	eve::grid::rotatedFootprintSize (int w, int h, const std::vector< uint8_t > &mask, int steps, bool hexMode, int &outW, int &outH)
	Axis-aligned size of a footprint after rotation.
