Textura de Fluxo de Lava Contínua para Three.js

Generate a high-quality, seamless, repeatable [lava flow] texture optimized for three.js materials. Ensure the texture has uniform lighting, no visible borders or seams, and maintains consistent color, density, and scale across the entire surface. The [lava flow] should feature glowing molten cracks, transitioning cooled crusts, and subtle subsurface scattering for realism. Include emissive regions, dynamic crack patterns, and PBR-ready maps (normal, roughness) for depth and adjustability. Render the texture top-down with even distribution, suitable for infinite repetition in any direction.
