/*
 * timeline.css — Team Portal UI primitive: generic vertical timeline.
 *
 * Companion to lib/timeline.js (block 9 of task radar-os--464-history-tab-all-modes).
 *
 * Dot colors via `--badge-{variant}-color` from status-badge.css palette.
 * Graceful degradation when CSS-vars missing (fallback colors hardcoded).
 *
 * No emojis (memory rule).
