Sierra 750: from data to package

Fictional bottle example: names, documents and tests are demonstrations, with data dated 15 July 2026. Load Sierra 750 or import the downloadable draft to reproduce it. The sample data are in Spanish.

Checks

Compare three versions of the same draft: A, original; B, the steel percentage reference left blank; C, steel changed to 80%, totalling 98%. B and C need review but do not block the ZIP. An individual value of 101% does block it. Obtain real documents and resolve warnings before publication.

QR · HTTPS

The example ZIP contains 10 files and no attachments. Extract index.html to view it, but its QR still points to the fictional example.com URL. For a real product, host the files at your HTTPS address, confirm that address and test the QR from another device. Downloading or checking the QR inside the app does not publish the page.
