// Output tests for the `box-shadow` mixin in scss/mixins/bootstrap/_box-shadow.scss.
// With `$enable-shadows: true` (the default) it filters out null values, keeps a
// single keyword (none/inherit/...) as-is, and otherwise joins the shadows into a
// comma list. The `$enable-shadows: false` gate depends on overriding that global
// and is not covered here.
