Silhouette: A four-way relay knot whose channels remain separate through the convergence, with handoff tokens resting at each explicit boundary. Materials: Dark ceramic conduit, braided natural fiber, machined nickel collars, and four distinct but restrained material-coded tokens. Spatial rhythm: Four equal approaches, bounded center, no superior axis, ample stop-space between handoffs. Visualize a public product identity and operational instrument, not a mythological deity, generic robot, humanoid mascot, or autonomous authority.",
