Three functions and you've got a game. The console calls init
once, then runs update and
draw sixty times a second on the DMG screen.

No build step, no toolchain — it compiles in the browser.
The cart appears on your shelf with a generative starburst label seeded by its name, and it's
saved to that device in localStorage. It's yours, it persists, it's playable.
A cart that throws gets caught and shown a green crash screen — never a dead console. Fix it, burn again.
Type a sentence into Dream-a-Cart — "a fishing game with a shark" — and a real, compile-tested cart gets written and burned for you. Free local engine always on; optional LLM upgrade if you deploy the dream service. (See Guide 02.)
When your cart is slotted, a share bar appears — copy a play link or post it to X. Friends who open it get your cart auto-booting with a SPECIAL DELIVERY banner and a BURN ONE BACK button.
