A second copy of a family LibreOffice bundles makes its render
non-deterministic: it resolves the same family to either file per run — the PDF
names them Carlito and Carlito-Regular — and their vertical metrics differ, so a
page led by a large-font heading lands 1.85mm lower on some runs. Measured 5/5
identical once the duplicates were gone, against a 2-of-4 flip before, and one
fixture's count swinging 21↔62 with no code change. README now says to install
only what the local LibreOffice does not already ship.
Also skips the `~$name` lock file a word processor leaves beside a fixture it
has open, which the corpus was picking up as a document.
