219b4b1605* fix(pdf-server): remove page-loading overlay The overlay had multiple issues: - Hardcoded white background broke dark mode - Could get stuck visible, breaking sizing/layout - Added little value since previous page stays visible during render and the 150ms delay meant most renders completed before it showed * prettier:fix
