Build a retro arcade Breakout game as a static page in this directory: index.html, style.css, game.js. Canvas gameplay with paddle, ball, brick rows, lives, score, levels with increasing speed, particle effects on brick hits, WebAudio sound with a mute toggle, pause overlay, high score in localStorage, dark neon theme. Also create tests.html + tests.js exercising the core physics/collision logic. Run the tests headless with node and fix what fails.
