Fix documentation: missing Paginable.

Separate internal plain Paragraph/ParagraphLayout.

Expose text slicing functions.

Fix style: white space in exports and imports.

Prepare pagination for future layout types.

Add paragraph pagination.

Better format ParagraphConstruction documentation.

application.

Slightly decompose the Plain module.

Update documentation and derived instances.
