🔗 Entanglement and the No-Signalling Limit: 2D Bell Test

Interactive 2D Bell/CHSH experiment with an entangled-pair source and two distant analysers: drag the analyser dials, watch correlations reach the 2.83 Tsirelson limit against the classical bound of 2, and try to send a message by changing Alice's setting to see why Bob's statistics never change.
