// Default document attributes matching `asciidoctor`'s behavior
//
// These universal attributes apply across all output formats and are
// automatically set when a Document is created. They can be overridden
// by document attributes (e.g., `:note-caption: Custom Note`).
//
// Format-specific attributes (like HTML's `lang`) should be handled
// by individual converters with appropriate fallbacks.

/// Includes:
/// - Character replacement / intrinsic attributes (empty, sp, nbsp, etc.)
/// - Admonition captions
/// - Block captions (example, figure, table, appendix)
/// - UI labels (TOC title, version label, etc.)

/// - Structural settings (TOC levels, section numbering depth)
/// - ID generation settings
/// - Attribute processing compliance settings
