Demo

Every icon below is converted from the current library when the site is built. Each card shows the source as it was drawn, with strokes, then the outline that unstroke makes from it as a single filled path, and an overlay with the source in blue on top of the outline in grey. When the result is right you only see blue. Any grey fringe means a mismatch. The bottom row is the same icon outlined at stroke widths 0.5, 1 and 1.5, all from the one source file.
