+;; This module acts as a facade for configuration management,
+;; aggregating specialized modules that follow single responsibility:
+;; - defaults: Pure data definitions
+;; - loader: File I/O operations  
+;; - accessor: Pure configuration value access
+;; - state: Mutable state management
+;;
+;; Both pure and impure functions are available, allowing callers
+;; to choose the appropriate level of functional purity.
