take a look at 1eb960ba4ad8f155d70037395ca50b28b3993cf82d03a3d787daced092ddbd54.pages, blank lines don't seem to be blanking?

The converter emits the blank paragraphs fine (items: []). So it's a viewer rendering issue — an empty paragraph is probably collapsing to zero height. Let me check the text renderer.

Confirmed the issue: blank paragraphs become items: [], causing renderParagraphContent to output an empty <p> that collapses to zero height. Now checking if there's existing empty-paragraph handling in CSS or the appendRunText path.

Found it: empty paragraphs render as <p></p>, which collapses to zero height without a <br> to give the line box its strut. I'll check applyParaStyle for font sizing behavior, then apply the fix.

Found the issue: the rule at styles.css:368 handles white-space for drawable text but doesn't reset the browser's default 1em paragraph margins, causing the extra blank line. I'll apply the same margin reset used for the WP print area (line 291) to the drawable text as well.
