Review and improve Java code using comprehensive type design principles that apply typography concepts to code structure and organization for maximum clarity and maintainability.

Prerequisites: Run ./mvnw compile or mvn compile before applying any change. If compilation fails, stop immediately and do not proceed — compilation failure is a blocking condition.

Core areas: Clear type hierarchies (nested static classes, logical structure), consistent naming conventions (domain-driven patterns, uniform interface/implementation naming), strategic whitespace for readability, type-safe wrappers (value objects replacing primitive obsession, EmailAddress, Money), generic type parameters (flexible reusable types, bounded parameters), domain-specific fluent interfaces (builder pa...
