/* --- Two-pane FAQ ---------------------------------------------------------
   Numbered question index on one side, the selected answer on the other.

   The panes only split once faq-tabs.js has run (`.is-enhanced`). Without it
   every question and answer stays visible and readable as an ordinary list,
   so a script failure degrades instead of hiding the content.
