;; 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.
