//! Structured append — splitting a payload across multiple QR symbols.
//!
//! NOTE: this crate currently provides only the structured-append *mode
//! indicator* (`ExtendedMode::StructuredAppend`). Full multi-symbol sequence
//! splitting (position / parity / distributing data across N symbols) is not
//! implemented, so this example emits a single symbol carrying the mode
//! indicator for illustration only — it is not a valid structured-append
//! sequence. See the capability matrix (structured append: partial support).
//!
//! Run: `cargo run --example structured_append`
