Paints the studio scene at HDR (Float32 RGBA) precision. The
gradient sky, ceiling softboxes (cores), wall panels, and floor
checkerboard come from paintStudio with the LDR canvas
pixels read straight into the float buffer; the sun core and
softbox cores are then over-stamped at radiances above 1.0.
Pair with encodeRadianceHDR and pass the result to
IBL.setEnvironmentHDRBuffer to drive the renderer's HDR IBL path.
