 This is the S2 migration of the progress circle. The original markup has changed to an svg and circle element to allow CSS styles such as `stroke-linecap`. This was necessary to match the design. The `--small/--medium/--large` sizing classes have been deprecated in favor of t-shirt classes `--sizeS/--sizeM/--sizeL`
