v1.76
- Kept the keyboard pattern preview aligned with the final stripe CSG output.
- Kept color-only preview updates instant unless the color change alters same-color legend inversion geometry.
- Forced the required inversion rebuild even when automatic rebuilds are off.
- Matched keyboard-view stripe sampling to final CSG cutter quality and hid fallback guides when final CSG meshes are available.
- Optimized straight, gapped stripes with one disjoint Manifold cross-section while preserving explicit unions for deformed bands.
- Use a bounded two-worker pool for non-raft exact builds when the browser has multiple hardware threads; raft builds retain the single-worker path.
- Keep the pool opt-in with
?parallel=2until it demonstrates a win on the target browser and mesh.
