5/// Represents a single layer of the `stroke` shorthand.
6///
7/// The `stroke` property is a shorthand for `stroke-image`, `stroke-position`,
8/// `stroke-size`, `stroke-repeat`, `stroke-origin`, and `stroke-color`,
9/// modelled on `background`'s `<bg-layer>#` grammar the same way `fill` is
10/// (see `FillLayer`). The `color` field is only meaningful on the final
11/// layer, but we parse it permissively on every layer, matching `BgLayer`'s
12/// approach.
