+ * @file flash_namespace_config.h
+ * @brief Configuration file for Flash namespace management and isolation
+ *
+ * This header provides configuration macros for managing the Flash namespace
+ * across a codebase. It allows for flexible namespace naming and provides
+ * utilities for namespace declaration and scoping.
+ *
+ * Usage Examples:
+ *
+ * 1. Basic namespace wrapping:
+ * @code
+ *   BEGIN_FLASH_NAMESPACE
+ *   class FlashDevice {
+ *     // Implementation
+ *   };
+ *   END_FLASH_NAMESPACE
+ * @endcode
+ *
+ * 2. Accessing types within the namespace:
+ * @code
+ *   FLASH_NAMESPACE_ALIAS(FlashDevice) device;
+ * @endcode
+ *
+ * 3. Defining content within namespace scope:
+ * @code
+ *   FLASH_NAMESPACE_SCOPE(
+ *     struct Configuration {
+ *       uint32_t size;
+ *       bool enabled;
+ *     };
+ *   )
+ * @endcode
+ *
+ * 4. Custom namespace name:
+ * @code
+ *   #define FLASH_NAMESPACE flash
+ *   #include "flash_namespace_config.h"
+ * @endcode
+ *
+ * Configuration:
+ * - The default namespace is 'flash' if FLASH_NAMESPACE is not defined
+ * - Define FLASH_NAMESPACE before including this header to customize the
+ * namespace name
+ *
+ * Best Practices:
+ * - Include this header in all files that need access to the Flash namespace
+ *
