Each part of you is a rung on a strand. The free quiz sequences the six core rungs, and every deeper lens extends the strand, so more of you gets sequenced. This is the D direction.
The seed shifts the twist of the helix, so two identical profiles never render the same strand.
Working review prototype. No data saved or sent. Paid-lens values are samples to show the growth. Share image is always the coarse, flattened version.
