//! Low-level storage layer
//!
//! This module provides the foundation for disk-based storage:
//! - Page management (4KB fixed-size pages)
//! - File I/O with memory-mapped files
//! - Free space allocation
//! - Buffer pool with LRU caching

// Hardened durability core (allocator, buffer_pool, file_manager, page,
// superblock) compiles strictly; peripheral storage engines keep a scoped
// dead-code allow (they predate this durability pass and are out of scope here).
