/* ots.gg stats -- dashboard styling.
 *
 * Colour tokens follow the `dataviz` skill's validated default palette (categorical hues
 * pass the CVD/contrast checks in both modes; see the skill's references/palette.md for
 * the underlying numbers). Light is the default; dark is picked up from
 * prefers-color-scheme, since this dashboard has no theme toggle of its own -- an admin's
 * OS setting is the only signal available, and honouring it is enough for an internal tool
 * with a handful of users.
 *
 * Every colour is a custom property, read here AND by public/dashboard.js (Chart.js
 * cannot read CSS variables itself, so dashboard.js resolves them once via
 * getComputedStyle and passes the resolved hex into the chart config).
