- ///
- /// - A length specifying the stroke's thickness. The color is inherited,

- /// - A color to use for the stroke. The thickness is inherited, defaulting
- /// to `{1pt}`.
- /// - A stroke combined from color and thickness using the `+` operator as
- /// in `{2pt + red}`.
- /// - A stroke described by a dictionary with any of the following keys:
- /// - `paint`: The [color]($type/color) to use for the stroke.
- /// - `thickness`: The stroke's thickness as a [length]($type/length).
- /// - `cap`: How the line terminates. One of `{"butt"}`, `{"round"}`, or
- /// `{"square"}`.
- /// - `join`: How sharp turns of a contour are rendered. One of
- /// `{"miter"}`, `{"round"}`, or `{"bevel"}`. Not applicable to lines
- /// but to [polygons]($func/polygon) or [paths]($func/path).
- /// - `miter-limit`: Number at which protruding sharp angles are rendered
- /// with a bevel instead. The higher the number, the sharper an angle
- /// can be before it is bevelled. Only applicable if `join` is
- /// `{"miter"}`. Defaults to `{4.0}`.
- /// - `dash`: The dash pattern to use. Can be any of the following:
- /// - One of the predefined patterns `{"solid"}`, `{"dotted"}`,
- /// `{"densely-dotted"}`, `{"loosely-dotted"}`, `{"dashed"}`,
- /// `{"densely-dashed"}`, `{"loosely-dashed"}`, `{"dash-dotted"}`,
- /// `{"densely-dash-dotted"}` or `{"loosely-dash-dotted"}`
- /// - An [array]($type/array) with alternating lengths for dashes and
- /// gaps. You can also use the string `{"dot"}` for a length equal to
- /// the line thickness.
- /// - A [dictionary]($type/dictionary) with the keys `array` (same as
- /// the array above), and `phase` (of type [length]($type/length)),
- /// which defines where in the pattern to start drawing.
- ///
- /// ```example
- /// #set line(length: 100%)
- /// #stack(
- /// spacing: 1em,
- /// line(stroke: 2pt + red),
- /// line(stroke: (paint: blue, thickness: 4pt, cap: "round")),
