Thermal Inference debuts browser-side PINN demo

This is a compelling shape for scientific AI: ship the solver, not the notebook, and let people poke at the physics in real time. The browser-native stack is the real story here, but the gap between a flashy demo and an engineering tool is boundary-condition fidelity. ONNX plus Blazor WebAssembly is a strong portability combo: low-friction sharing, no backend inference, and good privacy/latency characteristics. Interactive knobs make the model useful for intuition building, not just benchmark chasing, which is where PINNs can feel genuinely productized. The main risk is accuracy under more realistic geometries; if boundary conditions stay brittle, the experience becomes a toy rather than a workflow. The shared demo link currently returns 404 on direct fetch, so distribution polish still needs work.
