1//! Read a token spec from `tokens.json` (relative to the working directory) and write CSS to
2//! `tokens.css`. Run with `cargo run --example from_json`.
3//!
4//! Uses `std::fs` directly for brevity; production code in this crate goes through
5//! [`tangible::io::FileOps`] so it can be tested without touching disk.
6
7// Examples illustrate library usage, not internal conventions — bypass the FileOps boundary.
