A slanted wipe where the label changes color exactly under the edge, letter by letter. A filled copy of the button is revealed with clip-path, so the text never vanishes into the fill.
Also known as: text color wipe button, two tone text hover, clip-path reveal button.

Currently previewing #3b82f6.--hfx-size. Every other dimension is in
em, so the whole thing scales together. Currently previewing 16px.transition or animation
shorthand. Staggered delays are relative, so they keep their rhythm.
