GrassKind (grass_kind.ludic) carries what grass.ludic, grass_gpu.ludic, grass.vert, grass_cull.comp and model.frag's BLADE path held as constants: the cell, s0 / d0 / radius, the row bands and rows, the blade profile (neck, root, swell, tip, bend), the heights, clumps, widths and arch, where it grows (slope, snow, the photograph's test), the root / tip / gone-to-seed colours, the far tufts, the root occlusion, the roughness, the sheen and the wind. Its defaults are those constants exactly, so a game that sets nothing draws as before. The shaders read them as u_gk_* (the cull as five more Params vec4s, 288 bytes); grass_reset.comp writes each band's index count so a kind of other rows reaches the draw in order. grass_quality holds the kind to a settings tier (never denser, never farther); R3D_GRASS_* still win. grass_profile_w / _bend are the one profile, for the meshes and a game's preview. grass.mesh takes only the cell: the rest of it is an older copy that already differs from grass.vert, left as it draws.
