GradientText

Composes with the classes `Box` computes instead of replacing them.

The element it paints — inline, so a gradient run can sit inside a heading. Keep the text short whatever tag you pick: the clip works per line box, so a paragraph gets the whole gradient over again on every single line.

The colour painted whenever the clip cannot be: no browser support, Windows forced colors, and the underline, which would otherwise be clipped away to nothing. It is not decoration — clipped text is transparent, so this is the only thing between a failed gradient and invisible text.

A theme gradient role, or a literal `{ from, to }` pair. The role is resolved against the live theme and follows a theme switch; a literal pair is frozen where you wrote it.

Takes family, size, weight, line height and tracking from the parent instead of the component's own. What you want for a gradient word inside a heading, so it does not resize the line.
