/* Button — pill-shaped and monochrome: a filled foreground action by default, secondary for
   the tonal one, outline for the bordered one, ghost for a surface that only appears on
   hover, link for inline text actions.

   Filled variants are lit from above by two layers that sit between the fill and the label:
   - `::before`, the wash: a blurred copy of the shape raised by half its height, so only its
     soft lower edge glows inside the upper half. `filter` runs before `clip-path`, which lets
     one box blur itself and still be cut back to the button outline.
   - `::after`, the rim: a half-pixel ring whose colour fades out towards the bottom. A
     box-shadow cannot take a gradient and `border-image` ignores the radius, so the ring is
     a gradient box with its content box masked out. */
