Human Currency · Contribution
Contribution is the chance to carry real weight for the group. A person grows into their full capability by carrying it, and nobody can carry it for them.
Belonging settles the nervous system, and a settled person can do hard things. Contribution earns recognition, recognition deepens belonging, and the loop compounds. A team running both currencies lives on the surplus.
