Freeform interlocking fill-in puzzles from a themed word list: the grid shows empty slots, the bank groups words by length, the solver fits them together. Every word must interlock or the batch fails loudly; an independent gate verifies no unintended words form. Dense American-style crosswords are out of scope.
