//! Sparse array storage formats and operations.
//!
//! This module provides sparse matrix formats (CSR, CSC, COO, block-sparse)
//! for efficient representation and manipulation of sparse data structures.
//! All formats implement a common trait surface for backend-agnostic operations.
// Re-export common types
