A2UI Atomic Catalog Real rendered UI in the conversation — charts, gauges, dashboards, study apps — without the model writing a single line of HTML.

• List Catalogs: List every A2UI catalog with a when-to-use, so you can pick the extension catalogs a surface needs. The base catalog (a2ui-atoms-v1) is always resolved.
• Get Catalog: Return one catalog's atoms (type + one-line description) so you know its vocabulary.
• Required Catalogs: Given an A2UI payload, return the resolvable catalog URIs it needs (deterministic — pure function of the atoms).
