Tested result & sample
11zon offers a very handy dual-tab interface ('Slider' by % and 'Size' by target KB), shrinking our 4.14 MB PNG down to 842 KB (-79.65%) in 1.8s at its default 60% level; however, the aggressive palette cut causes visible gradient banding (PSNR=32.83 dB) and users must dodge 3 green 'DOWNLOAD EXTENSION' fake ad buttons (02_workspace.png).
