FAQ
Do the words need the same length?
Yes. Word ladders only work when the start and end words have the same number of letters.
How many words are in the graph?
This version uses a curated set of four-letter ladder words for clean demo behavior.
Does it always find the shortest ladder?
Yes. The solver uses breadth-first search on the local word graph.
