Clonal Selection Logic:
1. Naive B-Cells: Billions exist, each with a unique, randomly-generated receptor geometry.
2. Antigen Binding: Only the specific B-Cell whose receptor perfectly fits the pathogen's epitope geometry will bind.
3. Clonal Expansion: The selected B-Cell proliferates into Plasma cells, mass-producing millions of identical targeted antibodies to neutralize the infection.
