// 🌍 This code is free. Like speech. Like people should be.
// Use it, learn from it, build with it. Share what you make.
// But remember what this is for: not greed, not ego — but freedom, creativity, and unity.
// 
// Inspired by Chaplin's call in The Great Dictator:
// “You, the people, have the power — the power to create happiness!”
// 
// So build not for domination, but for decentralization.
// Not for walls, but bridges. Not for power, but empowerment.
// 
// Licensed under the MIT License — short, sweet, and to the point.
// No restrictions, no delays. Just create. Just be human. ✌️
