//! `cargo xtask assets`: enforce the asset policy (AGENTS.md §1).
//!
//! `ATTRIBUTION.toml` lists every asset: committed or vendored files (`[[asset]]`), files that
//! Cargo dependencies compile into PdfCraft (`[[bundled]]`), and files xtask downloads at build
//! time (`[[fetched]]`). This gate fails when:
//! - an asset-like file in the repository has no entry, or its SHA-256 differs;
//! - a licence is not on the allowlist, or a declared licence file is missing;
//! - an icon, image or font names Adobe as author or source, or an `adobe_data` entry is not on
//!   the closed list approved in AGENTS.md §1.1;
//! - a `[[bundled]]` crate version is not the one in Cargo.lock;
//! - `ATTRIBUTION.md` is out of date (`--write` regenerates it).
