Module document 

Structured display blocks used as the boundary between formatting and terminal rendering.

This module exists so higher-level code can describe what should be shown without deciding how it should be painted in a terminal. Formatters build documents out of semantic blocks, and the renderer later turns those blocks into themed terminal text.

In practice, this keeps rendering bugs easier to localize:

• if the document shape is wrong, the formatter is wrong
• if the document is right but the terminal output is wrong, the renderer is wrong

Contract:

• document types may carry semantic styling hints and layout intent
• they should not depend on terminal width probing, theme resolution, or config precedence
• block variants are intentionally higher-level than raw ANSI/text spans so multiple renderers can share the same model
