//! Module: sns::report::neurons_cache::storage::lookup
//!
//! Responsibility: resolve SNS neuron cache input to a complete cached snapshot.
//! Does not own: CLI argument parsing, refresh collection, cache rendering, or live fetches.
//! Boundary: supports numeric SNS ids and root canister principals over local cache files.
