We propose Quantum Fluid Spacetime Theory (QFST), a framework in which spacetime at galactic scales behaves as a turbulent, viscous fluid. A rotating galaxy induces a large-scale vortex generating pressure gradients that naturally produce flat rotation curves without dark matter particles. Proof of concept fit on NGC 3198 achieves chi2ᵣed = 0. 678 vs NFW chi2ᵣed = 1. 219. Code available at GitHub.
