Cosy Nonogram Game Builder

One prompt that builds a complete cosy nonogram (picture logic) game in a single HTML file, art drawn in code, with two twists: every puzzle is proven solvable by logic alone, with no guessing, and every solved picture comes alive in an album. 100+ puzzles in 4 chapters, colour puzzles, mosaics, places to restore, a daily puzzle, achievements, hints that explain one proven cell, touch, pinch zoom, keyboard, synthesized music, attract mode and a demo switch.
