/* Debt splitting feature styles.
   Self-contained: all class names are prefixed with `debt-` so they
   can't collide with existing component/page styles.
   Uses CSS variables already defined by theme.css (falls back to the
   same tokens used elsewhere in the app so light/dark theme switching
   works correctly). */
