The Syro code is our upgrade to legacy four-letter typing — a richer eight-function read, not the same system. The four-letter label appears in brackets for reference only. A gender modulator (M/F) is coming soon — it meaningfully shifts how each type expresses.
- You run on different channels — which is exactly what makes you interesting to each other.
- One of you opens up wild possibilities, the other senses which one's right.
- One of you chases the moment, the other keeps you both grounded.
- One of you drives things forward, the other makes sure the logic holds.
- One of you reads the mood between you, the other keeps it honest.
