+"I've wanted to change this website's favicon from a plain `.ico` file to a "
+"proper SVG. The problem I was trying to solve was to reuse the same image on"

+"Generating a PNG from the existing 16x16 icon was possible but bad: the "
+"final image was blurry. Converting the `.ico` to an SVG was possible, but "
+"sub-optimal: tools try to guess some vector paths, and the final SVG didn't "
+"match the original."
