Track completion rate from URL paste to successful download (or honest failure). Segment by device class to see whether international audience notes changes outcomes on phones vs desktops.
If you publish changelogs, reference guide #402 when you ship related fixes so internal search stays coherent.
Keyboard and screen-reader basics for form UX

Semantic headings let assistive tech users jump between sections the same way sighted users scan H2s.
