The Challenge Rendering a complex 153-concept-node, 1,200-edge mythic relationship topology for mobile devices without triggering main-thread layout thrashing or heavy client-side JavaScript execution. The Technical Approach Build-Time D3 Force Layout Computation : Pre-computing node coordinates and physics simulation during the Astro static build step. Zero-Runtime SVG Pre-rendering : Outputting the rendered topology as inline SVG with CSS design tokens, preserving 6...
