Initial 8,598 dataset diversity analysis

RCSB structural-cluster annotation is reported only where source-linked PDB entity mapping is available. UniProt annotations are limited to cached exact-sequence matches. Local 3-mer cosine similarity is a sequence-screening proxy, not alignment-derived percent identity.
