/* dots.css — Dots component styles.
 *
 * Every colour is read from a site token with a fallback, so this file drops
 * into the Amber website (which defines --accent, --surface, --border, …) and
 * also works in the standalone folder, where index.html defines the same
 * handful of tokens itself. The renderer reads --dots-pos / --dots-neg /
 * --dots-bg from the document, so retheming the dots is a CSS change.
