Brick Breaker: one-prompt HTML5 arcade game for Claude Code

One paste in Claude Code builds a complete brick-breaker arcade game: a single index.html with HTML5 Canvas and vanilla JavaScript, no build step, no assets, runs offline from a double-click or any static host. Three levels with set layouts and rising speed, mouse, touch and keyboard paddle, angle-of-impact bounces, lives, score, saved high score, pause, particles and synthesised sound. Phased prompt: say "continue" twice. Same game as the video; visual details vary between runs.
