/* ---------------------------------------------------------------------------
   Decision tree — the Article 50 labelling tool, and the risk classifier later.

   Loaded only on pages that declare `tool: "decision-tree"`, so the other 45
   pages do not pay for it. Rendered entirely by /assets/decision-tree.js; the
   mount stays [hidden] until the JSON has loaded, so a failed fetch leaves no
   dead skeleton on the page.

   This file is identical on promptguide.no and promptworkbook.com, and
   check-parity.mjs fails if it stops being.
