5/// Represents a single layer of the `fill` shorthand.
6///
7/// The `fill` property is a shorthand for `fill-image`, `fill-position`,
8/// `fill-size`, `fill-repeat`, `fill-origin`, and `fill-color`, modelled on
9/// `background`'s `<bg-layer>#` grammar (fill has no `<bg-clip>`/`<attachment>`
10/// equivalent). The `color` field is only meaningful on the final layer, but
11/// we parse it permissively on every layer, matching `BgLayer`'s approach.
12///
