🧪 Wellness Holistic Wellness Simulation

Real wellbeing is not one number — it is four interacting systems: physical health, mental clarity, emotional resilience and social connection, each pulling on the others. This simulator models that as a coupled dynamical system: sleep, exercise, stress and social-time sliders set daily targets for each dimension, and the four scores relax toward those targets over simulated days with realistic lag and cross-coupling, exactly like allostatic load models used in health psychology. The live 3D tetrahedron stretches each vertex outward with its dimension's score and animates particles along its edges to show how strongly each pair of dimensions is currently pulling on one another, while the sparkline tracks the overall wellness index across the last 60 simulated days.
