/// A `RandSource` that uses the thread-local RNG (`rand::rng()`).

/// This RNG is fast, cryptographically secure (ChaCha-based), and automatically
/// reseeded periodically.

/// Each OS thread has its own RNG instance, so calls from multiple threads are
/// contention-free and safe. This type does **not** store the RNG itself; it
/// simply accesses the thread-local generator on each call.
