All walkthroughs

Each walkthrough names one behaviour, says where the logic usually lives, and stops at a rule you can re-own. They are field notes, not vendor documentation.

Games: the dinosaur jump, night mode, 2048's next tile, and the Tetris 7-bag. Files: PDF structure and blend-mode math. Clipboard: the copy that fails without an error. Login: why an expired code still works.

If you have not set an agent up yet, start with the 6-step loop and Claude Code setup.
