/* =============================================================================
   Revenue Recovery AI — public interactive demo (synthetic data)
   Hand-written CSS. Extends site/styles.css, which must be loaded first: the
   design tokens (--surface, --line, --green, ...), .wrap, .card, .tag, .btn,
   .stats, .ticks/.crosses, .table-wrap, .callout and the site chrome all come
   from there. This file only adds what the demo needs.

   Constraint that shapes everything below: the hosting Content-Security-Policy
   is `style-src 'self'`, so there is not a single inline style attribute and no
   script may set one. Every visual state is a class or a native <progress>.
