pub fn parse_score(cells: &[TextCell]) -> Option<f64>Expand description
The page parse_score: the 10th-percentile rate_text_quality over the
extracted text-layer cells (the quantile emphasises problem cells, matching
docling’s page-preprocessing stage). Unset when the page has no text layer
(a scanned page — docling’s nanquantile([]) is NaN there too).
