verve.gl — tone-mapping

A bright emissive PBR cube through the post-processing pipeline with a selectable tone-mapping operator. Cycle through Linear, Reinhard, Reinhard-extended, ACES (default), AgX, and Uncharted2/Hable. Toggle Vignette darkens the corners with a smoothstep falloff applied AFTER tone-mapping. Renders through WebGPU when available, else WebGL2.
