 * Results view (WP08): move annotations (move-extras.js), detail panel
 * (<hokito-detail-panel>), evaluation graph (<hokito-eval-graph>) and analysis
 * bar (<hokito-analysis-bar>). Tokens only (tokens.css), light and dark.
 *
 * Labels: `.label--<name>` sets --label-color from the --label-* tokens. The
 * colour always comes with an icon and a word (NFR-008); in the graph the
 * marker shape differs per label as well.
 *
 * Phone (below 720 px): controls wrap, the annotation word is dropped from
 * the move strip (icon, points and depth stay; the full text is in the
 * visually hidden summary), the graph is lower.
