 * Re-runs `correct` on every event that can change the panel's box:
 * - the wrapper's `style` mutations → floating-ui (re)positioning, incl. the
 *   async transition from the off-screen sentinel to the final coordinates;
 * - the content resizing (dynamic item lists) — also fires once on observe,
 *   covering a wrapper already positioned when the ref attached;
 * - viewport resize.
 * Returns a cleanup that detaches everything.
