Publish the already signed, notarized, and stapled PreviewMD 1.9 (13) installer through the production landing page. Update every download link, displayed version/build, JavaScript download filename and asset cache version; replace the previous public DMG and update the release receipt.

The installer bytes are unchanged from the Apple-accepted local release built from f8c4fdb23e758dd46b5d8c7dc15296dcfb6d84ab. Production deploys this tracked DMG through the documented GitHub → exp-deploy update previewmd path. No application code, licensing/ownership, API implementation, or subscriber database configuration changes.

Validation:

• 9 Python landing/API tests and 8 Node signup lifecycle tests pass; public links/version/build/path/size/SHA-256 match the release receipt.
• App, Quick Look and DMG signatures verify; app and DMG stapler validation and Gatekeeper report Notarized Developer ID.
• Local browser opens with version 1.9, correct download links and no signup modal; source build inputs remain unchanged.
• Independent review reports no actionable findings. Both old local artifacts and the new accepted installer are preserved under dist/.
