Pixel-art stone brick wall with bevels and moss

Generate a tileable pixel-art brick or stone-block wall at a chosen art resolution: staggered courses, one-pixel mortar, light and shadow bevels on every brick, grain, cracks and moss, with per-pixel normal, height, roughness and occlusion maps. Use for castle, dungeon and town walls in 2D games.

Limits to consider

Stylized pixel art with a fixed light from the top left baked into the bevel colours; roughness and height are values per drawn class, and the normal map treats each art pixel as a flat facet. Bricks are rectangles cut at whole art pixels; there are no corner pieces, arches or openings. Courses are limited to a quarter of the art size so every brick keeps a face pixel. Output sizes that are not a whole multiple of art_pixels give art pixels of unequal widths. Occlusion is a blurred-height estimate posterized to eighths.
