…143) Extend the existing fast path to detect when all text nodes contain only whitespace (indentation, newlines between HTML tags). In this case, skip the micromark + innerHTML + DOM walk pipeline entirely and render nodes directly via renderSingleNode. For a {for} loop over 23 HTML cards, this eliminates ~97 redundant pipeline calls that account for 89% of wall time in Chrome profiles.
