/*
 * OVERFLOW CONTAINMENT — PR Throughput bar chart
 *
 * Problem: When a large date range is selected the throughput chart renders
 * up to MAX_THROUGHPUT_POINTS (104) flex children.  Without containment the
 * flex row overflows the .chart-container panel and bleeds across the page.
 *
 * Current fix: overflow-x: auto gives horizontal scroll when bars exceed
 * the container width.  min-width on .bar-container keeps bars legible.
 *
 * TODO (024-dashboard-scalability): Discuss longer-term options:
 *   a) Aggregate / bucket bars so fewer DOM elements are rendered
 *   b) Virtualise the bar chart (only render visible bars)
 *   c) Switch to <canvas> / SVG for large datasets
 *   d) Keep the scroll approach but add a zoom/pan control
 *
 * See also: MAX_THROUGHPUT_POINTS in throughput.ts
