A content management system may support a card engine to dynamically perform operations such as configuring content for display via a user interface and generating reports based on user behavior, account status, and business logic. In cooperation with a facts controller to provide facts that the card engine may access substantively in real time, a rules engine to provide constructs in the form of card definitions, and a development engine, the content management system may enable a content manager to effect changes to card and container definitions by providing or modifying rules and rulesets in the rules engine dynamically. Cards evaluated dynamically by the card engine may be transmitted to user equipment. In this way, the content manager may make content decisions in accordance with business logic and events occurring proximate to the user, thereby impacting the user experience and generating reports in a substantive and real-time fashion.
