1//! Random number generation implementations for different target environments.
2//!
3//! This module provides conditional compilation for RNG implementations:
4//! - Browser: Uses crypto.getRandomValues() via getrandom with "js" feature
5//! - NEAR: Uses env::random_seed() with enhanced entropy via ChaCha20
