render-dual-grid-tilesets

Renders top-down terrain from a 15-piece dual-grid tileset: the map is authored as painted logical cells, each rendered tile reads the four surrounding cells into a 4-bit corner mask, and a fixed mask-to-frame table picks the matching cell of a 4x4 atlas, with pseudocode and a worked example. Use when implementing, porting, explaining, or debugging dual-grid autotiling in a game engine or a custom renderer. Not for generating tileset art, for 8-neighbor blob or Wang-edge tilesets, or for isometric grids.
