Mandelbrot Explorer

This explorer keeps viewport coordinates in arbitrary-precision decimals, then renders the escape-time field asynchronously so we can zoom past ordinary floating-point precision without losing the exact center or scale state.

Implementation notes

Viewport math uses decimal.js so center and scale updates do not rely on standard floating-point arithmetic.
Rendering runs asynchronously in row chunks and cancels stale frames whenever the view changes.
Query parameters can seed the initial center, width, backend, palette, quality, and iteration budget.
