heerich.js: SVG Voxel Engine for 3D Scenes

heerich.js: a JavaScript library that builds 3D voxel scenes and renders them as crisp SVG vectors.

Key features:

• Four CSG-style boolean modes (union, subtract, intersect, exclude)
• Oblique and perspective camera projections
• Per-face SVG styling with position-driven callback support
• Box, sphere, line, and custom fill shape primitives
• Per-voxel axis scaling with configurable anchors
• Full DOM interactivity through data attributes on every polygon
• JSON serialization for save and restore

No WebGL, no canvas. Pure SVG output that scales to any resolution and works with standard DOM event listeners.
