Pixel-art tree canopy of shaded leaf clumps

Generate a tileable pixel-art foliage tile at a chosen art resolution: overlapping scalloped leaf clumps shaded in four tones with dark rims, single leaves or needle strokes, deep gaps, fruit and blossoms, with per-pixel normal, height, roughness and occlusion maps. Use for tree tops, hedges and jungle walls in 2D.

Limits to consider

Stylized pixel art with the light from the top left baked into the clump shading; clumps are scalloped discs with a dome height, not individual modelled leaves or branches. Clumps are painted from the top of the tile to the bottom, which suits a canopy seen from the front or slightly above. Fruit and blossoms are tiny fixed sprites. The normal map treats each art pixel as a flat facet. 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.
