Attribute map utility
---------------------

Expose a structured mapping of the voice design attributes described in
`prompt.txt` together with the inline emotion tags listed in
`emotions.txt`.  The module returns data that can be consumed by tooling
to programmatically build descriptions or sweep attribute combinations.
