"""Generate ``fixtures/docx/hyperlink-target-modes--<scheme>.docx``.

Parameterised across the 5 TargetMode axes described by
``features/docx/hyperlink-target-modes.json``.

Exercised URI schemes:

*   ``http``    - ``https://...``               - external, TargetMode=External
*   ``mailto``  - ``mailto:...``                - external, TargetMode=External
*   ``file-uri``- ``file:///...``               - external, TargetMode=External
*   ``relative``- ``../sibling/other.docx``     - external (rare but spec-allowed),
                                                  TargetMode=External
*   ``anchor``  - internal bookmark, no rel

CLI:

    --kind {url|anchor}   which target shape to emit
    --url <str>           external URL (required when --kind=url)
    --anchor <str>        bookmark name (required when --kind=anchor)
    --out <path>          destination docx path (repo-relative allowed)
