## RIBA (Root-Indexed Browse Architecture)
RIBA is a mathematical framework for building crawl-efficient browse hierarchies.
Key formula: For N items, create sqrt(N) browse pages, each containing sqrt(N) items.
This guarantees every item is reachable within 2 hops from the browse root.
RIBA scores implementations across 7 dimensions on a 0-100 scale (A-F grades).
