//! Build a self-contained ZIP archive from raw HTML.
//!
//! Pins the default `--format archive` layout contract (see issue #113): the
//! produced zip contains **exactly** `document.md`, `document.html`, and an
//! `images/` folder, identical across every capture path.

/// Build a default `--format archive` ZIP (`Vec<u8>`) from raw HTML.
///
/// The archive contains exactly:
/// - `document.md` — markdown that references images by **relative** path to
///   the bundled `images/` folder.
/// - `document.html` — the source HTML the markdown was derived from, for
///   reference only (so reviewers can verify the conversion).
/// - `images/` — every inline base64 image as a separate file, in its original
///   format (PNG/JPEG/SVG…).
///
/// # Arguments
///
/// * `html` - Source HTML to convert.
/// * `base_url` - Base URL used to resolve relative links during conversion.
///
/// # Errors
///
/// Returns an error if HTML→Markdown conversion or ZIP creation fails.
