TUCE 3D Brain Canvas

Offline-safe cognitive lobe sandbox (Three.js): cubic-Bezier jigsaw explode with displacement, neon synaptic flare then Bezier dim, hover raycasting, and right-click proxy-channel gates (proxy_stress / proxy_explore / proxy_urgency / proxy_calm). Telemetry talks to behavior-modulation routes when the hub API is up; lab flags default OFF. Engineering state only — no clinical labels.
