/**
 * Swatch, front-end styles.
 *
 * The shopper's moment here is the *pick*: the click that commits to a colour.
 * Swatch borrows the gesture from a paint-chip sample card, when you choose a
 * colour you circle it. So the selected swatch lifts off the card and a warm
 * vermilion "marker" ring strokes itself around the chip, the way you'd ring
 * your choice on a sample fan. One earned micro-interaction; everything else is
 * quiet and conventional.
 *
 * Built on themeable `--swatch-*` custom properties so themes (and the PRO
 * add-on) can override sizing and colours without fighting specificity. The
 * accent inherits the theme link colour where one exists, falling back to the
 * vermilion ink. Focus-visible rings, sufficient contrast and
 * reduced-motion-guarded transitions are baked in. No layout shift: the lift,
 * ring and notch all paint inside the swatch's reserved box.
