/* PolHunter embed. One line on a mission site:
     <script src="https://polhunter.com/embed.js" data-slots="3" async></script>
   plus, where a code may appear, elements with data-ph-slot="0" ... data-ph-slot="N-1".

   When a hunter arrives with ?ph=<token> (their own, from their PolHunter board) the token is kept
   in sessionStorage for this tab, and after the mission's dwell the code is fetched from
   polhunter.com and rendered in ONE of the slots (which one is picked per hunter per day). The
   request carries this page's Origin; polhunter.com answers only for the mission's own host and
   only after the dwell. Anyone else loading this page sees nothing at all. */
