/*
 * One stylesheet, no framework, no build step.
 *
 * The dashboard is a dense table of numbers, so the priorities are: figures that line up
 * (tabular numerals, right-aligned), enough contrast to read a percentage at a glance, and a
 * table that scrolls inside its own container rather than pushing the page sideways.
 *
 * Both themes are defined from tokens on :root, with the dark set behind
 * prefers-color-scheme, so the page follows the reader's system setting.
