/* =========================================================================
   Sangam Travels — Trip Sheet System
   Design system layered over Bootstrap 5.3
   =========================================================================

   Palette is taken from the brand mark itself: gold #E0AF2A on black. Gold is
   the accent, not the interface — it marks the active section, focus, and the
   lead chart series, and never has to carry small text on a light background
   where it would fail contrast. Primary actions are near-black, which is both
   the other half of the logo and the most legible button there is.

   Colour otherwise means one of exactly three things: over/under a limit, the
   direction money moved, or trip status. Everything else is neutral, because
   this is a ledger and the numbers are the content.
