"""Generate a ``fixtures/docx/font-color*.docx`` fixture.

Supports two modes:

- **Literal (legacy):** no arguments — writes
  ``fixtures/docx/font-color.docx`` with the hard-coded "Red text" +
  ``#FF0000`` shape. Retained so the pre-parameterised manifest form
  still works for anyone who pins this file directly.

- **Parameterised:** called with ``--color-rgb <RRGGBB> --text
  <text> --out <path>``. Writes the fixture to the given path with
  the specified colour and text. The ``features/docx/font-color.json``
  manifest's ``generator.arg_template`` field drives these args at
  expansion time.
