From the README

This project lets you zoom into, modify, and explore several fractal formulas in the browser. The standard renderer is fast and interactive, but it still hits floating point precision limits at relatively shallow zoom depths. An experimental deep zoom path is now wired in on top of ShaderPad and GMP-WASM.

Rendering is a two-pass pipeline: an iteration pass writes a per-pixel metric (smooth escape time, stripe value, packed visual data, coverage) to an RGBA32F framebuffer, and a display pass maps it through the palette, lighting, and an ACES tone map.
