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

Parameterised across the 3 external-URL schemes described by
``features/pptx/hyperlink-target-modes.json``: http, mailto, file-uri.

Each fixture is a one-slide presentation containing a textbox whose
single run is hyperlinked to the requested URL via the python-pptx
``run.hyperlink.address = <url>`` high-level API.
