/* LagCore Hub design system.
 *
 * Dark only. This is a tool that gets left open on a second monitor next to a console, and
 * a light theme nobody asked for is a light theme at three in the morning.
 *
 * Two rules the rest of the file follows. Colour carries one meaning, severity, so an orange
 * number means the same thing everywhere it appears and nothing else is tinted for
 * decoration. And every figure is monospaced and tabular, because a column that shifts while
 * it updates is a column nobody can read at a glance.
