 /**
  * @file FFI.h
  * @brief SpacetimeDB Foreign Function Interface (FFI) layer for C++ modules
- * 
+ *
  * This file re-exports the raw ABI functions with additional type aliases
  * and convenience functions. Since we now use C# style opaque types that
  * are ABI-compatible, no conversion is needed.
- * 
+ *
  * Organization:
  * - Raw C ABI with opaque types is in abi.h
  * - This file provides type aliases and convenience functions
- * 
+ *
  * Key Features:
  * - Type-safe opaque types prevent mixing TableId with IndexId etc.
  * - Full BSATN integration for all data operations
  * - Modern iterator API with proper resource management
  * - Comprehensive error handling with Status codes
- * 
+ *
  * Note: WASI shims for C++ standard library support are provided separately
  * in the module library implementation.
