Sliding Fifteen

How it was vibe coded

The opening prompt

Make the 15 sliding tile puzzle on a 4x4 grid (also 3x3 and 5x5 options). Shuffle only to solvable states by making random legal moves from solved. Smooth tile slide animation, move counter, timer, best per size in localStorage, new shuffle button, nice completion burst.
