Rough CSS borders with SVG filters feTurbulence and feDisplacementMap

Here's a really cool technique from Daniel Jones that uses the feTurbulence and feDisplacementMap filters in SVGs to create rough borders:

The <feDisplacementMap> SVG filter primitive uses the pixel values from the image from in2 to spatially displace the image from in.

<feTurbulence> - SVG: Scalable Vector Graphics | MDN

The <feTurbulence> SVG filter primitive creates an image using the Perlin turbulence function. It allows the synthesis of artificial textures like clouds or marble. The resulting image will fill the entire filter primitive subregion.

feTurbulence is one of the most powerful SVG filter primitives. The specification defines this primitive as follows: Thi
