+ * Default RNG factory for bitpacker-network.
+ *
+ * Wraps `cryptoRng()` from `@suaveplan/random` so callers don't have to
+ * reach into another package for the standard CSPRNG-backed source. The
+ * `cryptoRng()` factory throws `RANDOM.SOURCE.UNAVAILABLE` if the host
+ * environment lacks `globalThis.crypto.getRandomValues`; we surface that
+ * directly so consumers know to inject a seeded `Rng` in environments
+ * without a CSPRNG (or in tests that need deterministic replay).
