Description
BlackCat is a sci-fi messenger where messages follow the laws of Quantum Mechanics. You don't 'send' a text; you Box it. They don't 'read' it; they observe it. 📦 Schrödinger's Box: Send 3 texts in superposition. Only 1 survives observation. 🔒 Heisenberg's Lock: View content OR sender. Never both. ⏳ Quantum Zeno: Hold to freeze time. Experience pure OLED black, neon UI, and true kinetic chat powered by ANU Quantum RNG.

Could you build this?
Yes It is a gamified chat application implementing simple logic gates (e.g., randomly picking 1 of 3 options upon read, revealing either sender or text based on a toggle) on top of standard WebSockets/Firebase.
