// Three-panel cost breakdown: a stacked-by-week bar over time on top,
// and two side-by-side categorical pie charts below (cost share by
// lane + by carrier). The patterns repeat across spend dashboards;
// swap `weeklySeries`, `byLane`, and `byCarrier` to repoint.
//
// All three panels are theme-aware: bar colors come from
// chartColors via the wrappers; pies surface inline value labels so
// the panels read at a glance without leaning on the legend alone.
