The “Sphere Embrace”: how Noos embraces top contributors without a childish mascot.
In neurobiology, glial cells wrap axons in myelin sheaths to accelerate neural impulses. On Noos, as your explanations earn accelerations and enter the Wiki Synthesis, the Noos Sphere wraps your Identicon with Keplerian orbits and two quantum nodes on its shoulders.

Single dashed orbit with 1 bright polar node at the apex. Highlights those who passed the exam.
Two coaxial ellipses (±35°) wrap the avatar with two lateral nodes.
