 * its rounded-corner clipping and color accent bar; an in-tree popover
 * gets clipped by that and only the part that overlaps the card is
 * visible. Rendering the preview via ``createPortal`` to ``document.body``
 * escapes every ancestor clipping context, and ``position: fixed`` with
 * ``getBoundingClientRect()`` keeps it pinned next to the thumbnail
 * regardless of where the card sits in the grid.
