/* Nexus design-system tokens + primitive styling.
   Authored to run the nexus-app kit standalone (the original _ds_bundle.js /
   styles.css from the design-system repo were not shipped with the kit).
   Screen-level layout lives in kit.css; this file owns the tokens every kit
   references plus the look of the design-system primitives in _ds_bundle.js. */
