Coordinates live in the URL, so a bookmark or a copied link restores everything: position, formula, palette and shading. Beyond zoom 4·104 the renderer switches to emulated double precision in the shader, which is slower and reaches roughly zoom 1011. If a deep view shows blocky terracing, your GPU's shader compiler is optimising the emulation away — reduce the zoom or render on another device.
