/* Digi Puzzles — tally engine. One copy serves every tally page in reports/.
   Tally is a 4×4 calcudoku (KenKen-style), built 3 Nov 2026 for Lab on the
   house chrome (engines/house.js, engines/finish.js). The page supplies its
   puzzle as window.DN_PUZZLE before loading engines/tally.js.
   Edit here to change every tally; keep element ids and localStorage keys
   stable (dn-track.js and players' saved progress depend on them). */
