/* ============================================================================
   JN Music Royalty Calculator — design system

   Loaded after bootstrap.min.css (v5.1), so plain class selectors here win
   over Bootstrap's compiled defaults without !important. Bootstrap 5.1 does
   not expose component-level CSS variables, so the components we actually use
   are restyled explicitly below.

   The palette is monochrome ink to match the black JN Music Group wordmark,
   with a single blue accent reserved for interactive affordances (links,
   focus, active navigation) and the status colours.
