/*
 * Custom stylesheet for the News Sentiment Dashboard
 *
 * This file defines a simple darkâ€'themed layout for the dashboard. It
 * arranges the page into a sidebar for selecting sources and a main
 * content area containing statistics, charts, and headline lists. The
 * design uses CSS variables for colours so that the sentiment colours
 * remain consistent across widgets.
