3// TODO(nlopes): this could instead be impl ToString for InlineNode?
4//
5// To do so, we'd need to change Vec<InlineNode> to a newtype struct.
6/// Extract plain text from inline nodes, recursively handling formatted text.
7///
8/// This function recursively extracts text from all inline formatting nodes
9/// (bold, italic, monospace, etc.), which is useful for generating IDs,
10/// alt text, and other plain text representations of formatted content.
