Overview

The Nokogiri → GFM visitor. Splits into two passes over the bounded kit vocabulary: block-level elements (this class) produce Markdown lines separated by blank lines; inline elements (Inline) produce a single run of text. Unknown block elements recurse into their children (text survives, the wrapper is dropped), matching the issue's "recurse into children" rule.

Instance Method Details

#render(node) ⇒ Object

Render a container's block children, joined by blank lines. Blocks that yield nothing (whitespace-only text nodes) are dropped so no stray blank lines accumulate.
