  // ---- Generic dropdown wiring ------------------------------------
  // Any `[data-rio-dropdown]` wrapper that contains a
  // `.rio-dropdown-toggle` and a `.rio-dropdown-panel` gets the same
  // open/close machinery: click the toggle to flip `is-open`, click
  // outside to close, Esc to close. The CSS reads `.is-open` and
  // shows the panel + rotates the chevron.

  //     bounding rect, so it escapes the list card's `overflow:
  //     hidden` instead of being clipped below the last row;
  //   * only one row menu is open at a time;
  //   * outside-click, Esc, scroll, and resize all close it;

  // closes the menu rather than chasing the toggle, which is the
