No separate boxes. The deeper parts are fused to the core at the very pointers they belong to, all on one ground, so the whole thing is a single connected form. Each part grows to the size of the trait it is joined to, and the core shifts as it grows.
Working review prototype. One shared ground (the original medallion). Parts join at: connect → Emotionality, drive → Extraversion, live for → Openness, thrive → Conscientiousness (designed associations, pending psychologist sign-off). Each part's size scales with that trait's score. Sample values for the deeper lenses.
