Keep feature inventory, user-focused prioritization, draft confirmation,
article templates, screenshot guidance and publication checks in one guide.
Use separate new-feature, improvement and bug-fix sections, with explicit
image, replacement and verification markers in drafts.
Archive the unreleased update article and its evidence review, retaining
pending screenshots and release details. Remove the split guide files and
update release-runbook references.
Validation: documentation structure, draft markers, 59 local links and
anchors, and staged whitespace checks passed. No product code changed;
product tests and builds were not run.
