	FROM UNNEST(JSON_EXTRACT_ARRAY(css, '$.stylesheet.rules')) AS rule
	WHERE JSON_EXTRACT_SCALAR(rule, '$.type') = 'media' AND
	JSON_EXTRACT_SCALAR(rule, '$.media') = '(prefers-color-scheme:dark)'
	FROM UNNEST(JSON_EXTRACT_ARRAY(css.stylesheet.rules)) AS rule
	WHERE STRING(rule.type) = 'media' AND
	STRING(rule.media) = '(prefers-color-scheme:dark)'

	CAST(JSON_VALUE(summary, '$.bytesTotal') AS INT64) / 1024 AS total_kb,
	INT64(summary.bytesTotal) / 1024 AS total_kb,
