/*
 * ==========================================================================
 * POST-ROTATION BANNER
 * ==========================================================================
 * Dismissable warning banner shown on the first page render after a
 * URL-driven workspace switch (red-team A-2 / C-2 mitigation per
 * docs/plan/20260521-workspace-keyed-routing Phase P10d).
 *
 * The banner uses the warning status palette (--status-warning / -light)
 * to signal an unexpected workspace change without being alarming.
 * It sits above #main-content so it is always the first visible element
 * inside the main scroll region, matching the role="alert" position.
 * ==========================================================================
