/* Helix design-system foundation — tokens, reset, and the zoom scale. The UI shell layer lives in
   app.css. Zoom (S/M/L) works by changing the root font-size; everything in app.css is sized in rem,
   so one control scales text AND spacing together (the User-Banner zoom control persists the choice). */
