The Marin blog is at /blog/, with original community posts and selected Open Athena articles. New original posts use layout: post; only imported OA posts use post_kind: mirror, source_url, and an original-source canonical URL. See native blog authoring for a ready-to-copy Markdown template and the shared article layout. See the Open Athena sync workflow for checking/importing published Marin posts through draft PRs and validating the build. The sync does not install a recurring schedule or deploy changes.

The shared footer's theme control offers System, Light, and Dark on home and every blog page. Explicit choices persist in browser storage under marin-theme; System clears that override and follows OS changes. Initialization runs before styles to avoid a wrong-theme first paint. If storage is blocked, the control still works on the current page, and new pages fall back to System. Theme regression checks: node scripts/check_theme.js (also run by check_blog.py, so Node.js is required for the combined validation command). Imported scientific plots retain light drawing surfaces for their fixed source ink colors.
