/*
 * Circle of Fifths (/tools/circle-of-fifths/). Loaded after site.css; uses its tokens only.
 * Mobile first: circle, then the key details; from 1100 px the details sit beside the circle.
 * SVG text keeps var(--text) on light fills in both themes (the layout test measures SVG text against
 * the box behind the SVG, so text never sits on a dark fill).
