HTML export, plain text and rich copy read each paragraph, heading, cell and HTML block through the component's MarkdownReader (pin 1251221). Emoji, alerts, the TOC and inline tags match visual mode. Footnotes sit in place as [n]; link titles are not written. Three review rounds failed; round 3's one finding (a scan per footnote over open marks) is fixed with a growth regression, unreviewed.
