/* ============================================================================
   starwars-viz-kit — viz.css
   Reusable, build-step-free stylesheet for the Anthropic demo harnesses.
   Extracted/generalized from HOLOCRON-9 (institutional-memory). All classes are
   prefixed `vk-` so the kit can be dropped into any demo page without collisions.
   Pairs with viz.js (the VizKit engine builds the DOM these styles target).
