dsfb-semiotics-calculus 0.1.0

//! # `dsfb-semiotics-calculus` — CLI binary
//!
//! Generates the ten canonical DSSC figures (`fig01…fig10`), a JSON summary,
//! a Markdown report, and a ZIP bundle — all placed in `./dsfb-sc-artifacts/`
//! (or a directory specified with `--output`).
//!
//! ## Usage
//!
//! ```text
//! dsfb-semiotics-calculus [--output <dir>]
//! ```
//!
//! Exit codes:
//! - 0: all artifacts written successfully
//! - 1: I/O error (details printed to stderr)
