/* =====================================================================
   Bill Explorer
   Interactive sample bill for the "bill-explorer" content-strip style.
   Markup: includes/strips/bill-explorer.php

   - Self-contained: nothing here depends on main.css.
   - px only. styles.css sets html { font-size: 50px }, so rem sizing
     would blow up inside this component.
   - Specificity: strip themes in main-base.css recolour descendants, e.g.
       .content-strips section.colour :is(... p ...)            (0,2,3)
       .content-strips section.colour :is(.btn, button)         (0,3,1)
       .content-strips section.colour :is(.btn:hover, ...)      (0,4,1)
     Text rules below use three classes and every button carries
     .bx-btn plus its own class, so these rules win on every theme
     without !important or relying on stylesheet order.
