   The sticky site header is z-index 90. The panel was 86, so its top edge
   (title + close button) was drawn underneath the header and could not be
   clicked. Lift both above the header, and cap the panel's height so it always
   opens *below* the header instead of sliding under it.                     */

/* --- THE close bug ----------------------------------------------------------
   `.ask-panel{display:flex}` is a class selector, so it beats the browser's
   default `[hidden]{display:none}`. Setting panel.hidden = true therefore
   flipped the property but left the panel on screen — it could never be shut.
   This restores the hidden behaviour.                                       */
