//! `balance` command — sum per account per commodity, rendered as
//! a flat list or an indented tree.
//!
//! Runs after the filter phase, so the journal already contains only
//! the postings the user wants summed. The `--empty` / `-E` flag
//! controls whether accounts whose total nets to zero are rendered —
//! in both flat and tree mode.
