#328Embossed Foil Sticker

A five-point star press-embossed into a sheet of champagne foil. The star is an exact signed-distance field; its distance is shaped into a beveled height and the gradient of that height becomes a surface normal, so the emblem stands up as real raised relief. A key light circles the sticker and the outward-facing bevel walls glint one after another as it comes round, with a hard highlight line drawn along the rim by a smoothstep on the bevel band. The whole seal turns slowly and a fine foil sparkle rides the sheet. Move the pointer to grab the light and rake it across the emboss by hand.
