SVG — Scalable Vector Graphics is a language for drawing shapes and text using XML markup, right inside the HTML. Unlike images, every element in an SVG is a DOM node you can inspect, style, and manipulate.
Veyra embedded the token in an SVG illustration on this page. The text is there in the DOM, but it's been made invisible through SVG-specific tricks: fill-opacity, transform, and layering. The Elements panel will show you what the canvas hides.
