Articles now live at data/content/articles/{slug}.md — this is the path the
admin CMS reads from (admin/routes.py:1861) when rebuilding manual articles
via the publish pipeline.
Marketing assets moved to marketing/ at the project root.
All 14 article files (C2–C8 + C4 DE/EN) and 4 marketing files relocated from
scratch/ where they never belonged.
