Build a Conway's Game of Life explorer as a static page in this directory: index.html, style.css, life.js. Canvas grid with play/pause/step/clear, speed slider, drag-to-draw cells, a library of classic patterns (glider, glider gun, pulsar) placeable by click, wrap-around edges toggle, generation counter, dark theme, and tests.html + tests.js exercising the next-generation rules. Run the tests headless with node and fix what fails.
