1//! Interactive prompting helpers shared across commands.
2//!
3//! Each helper bridges flag-driven and interactive input: in interactive mode
4//! it prompts the operator, and in non-interactive mode it falls back to a
5//! default or fails with a "flag required" error. Used to resolve missing
6//! arguments, confirmations, and selections uniformly.
