/* Digi Puzzles — path engine. One copy serves every path page in reports/.
   Extracted 2026-10-15 from 2028-08-18-logic-path-0762.html by tools/engine-shells.js.
   The page supplies its puzzle as window.DN_PUZZLE before loading this file.
   Edit here to change every path; keep element ids and localStorage keys
   stable (dn-track.js and players' saved progress depend on them). */
