Build digital logic from scratch · NAND → Full Computer
🎓 Learning Method:
Start with only the NAND gate — the universal gate.
At each step, build a new gate from already-unlocked gates and it becomes available for future levels.
Testing runs on the server against the full truth table — no partial credit.
