"""Generate ``fixtures/xlsx/core-properties-full--<field>.xlsx`` fixtures.

Parameterised generator: one call per field under test. Mirrors the docx and
pptx counterparts and satisfies ``features/xlsx/core-properties-full.json``.

Fixtures are byte-reproducible: ``zip_date_time`` pins the zip-member clock
and ``created`` / ``modified`` are pinned to fixed ISO-8601 values.
