/**
 * ReportCharts (assets/js/report-charts.js): the hourly column chart and the issue ring.

 * Every colour is a CSS variable - the theme's (--text-color, --content-bg) and the plugin's
 * status colours - so dark mode and custom colours need nothing from the script. A chart
 * takes its colour from --rb-status, which its data-status sets, or which a parent sets
 * (the report box does, for its frame and count too).
