/* KiwiHacks design tokens and the handful of components that carry the

 *
 * The bulk of the rebrand happens in themes.css, which re-points the semantic
 * palette and the Tailwind --color-* tokens. This file adds the pieces that
 * need explicit opting into: the leaf-and-dashed primary action, the craft
 * card, the status chip, and the sky focus ring.
 *
 * Per the design language, use the expressive treatments on participant-facing
 * and public surfaces. Admin tables, scan history and event forms stay calm. */
