Rewrite every guide for the redesigned app, add guides for new features (documents, editor modes, check, cover letters, assistant, applications, self-hosting upgrade and environment reference), remove v5-only pages with redirects, and replace every screenshot.
Rewrites the landing page, in-app microcopy, and public docs, then fixes what the rewrite exposed: stale template counts, a broken quickstart anchor, out-of-sync FAQ structured data, dead error-hint branches in the MCP tools, and wrong-sense translations across all 53 locales. Adds GLOSSARY.md so translators get the right sense of the ambiguous UI terms.
