One self-contained file, loaded lazily so it never slows down this page —
works fully offline once it's loaded.
Your progress saves automatically — level, best score and your chosen wobble are
kept right here in this browser. No account, no sign-up, nothing to remember.
It's saved per browser, so it won't follow you to another device yet.
On iPhone, adding this page to your Home Screen keeps it safe indefinitely.
The real build is one self-contained HTML file — no ads, no tracking, works with the network off.
