feat(render3d): the meadow's blades are culled on the GPU - under 1.5 ms of a MoltenVK frame for all the grass
- grass_cull.comp decides each candidate blade once a frame (place, ground, density, water, slope, frustum, colour field) and writes survivors into three bands by distance, one indirect draw each; grass_inst.vert only bends and places the vertices. OpenGL keeps grass.vert's per-vertex path; R3D_GRASS_GPU=0 compares - compute programs take sampled textures after their buffers (gpu_compute_tex / gpu_dispatch_tex), and every dispatch now records a compute-to-draw memory barrier - the blades as a sward: 4 m cells, bands with five, three and one-quad blades, spacing doubling every 18 m to 70 m, never narrower than a pixel; lit facing the sun and leaning to the sky, shadow looked up above the ground (it read the terrain as its caster), a colour ramp that leaves only the sheath dark, clumps, dry patches and a tussock shade worked out per blade - scatter layers flagged grass are skipped while the blades draw (and under R3D_NOGRASS); R3D_BLADES, R3D_NOBLADES win over the game's setting; R3D_GRASS_S0/D0 for measuring Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
