canic-cli 0.71.1

//! Module: canic_cli::blob_storage
//!
//! Responsibility: expose operator CLI commands for blob-storage billing readiness.
//! Does not own: canister runtime billing policy, Cashier calls, or product orchestration.
//! Boundary: parses operator commands and renders host canister-call actions.
