//! The editorial poster: custom display faces (Playfair Display, OFL),
//! a deep-green duotone field, ochre accents, botanical path art — every
//! color through theme tokens. Opens in a window by default;
//! `cargo run --example poster -- shot` renders gallery/poster.png
//! headlessly instead (the README art).
