Iron Division audio
===================
Sound effects (assets/audio/*.ogg): original synthesis, tools/sound/sfx.py (numpy/scipy). No recorded
or third-party samples. Categories mirror the original A.R.S.E.N.A.L. sound banks, but no audio,
text or data from that game is used.

Voice lines (assets/audio/voice/*.ogg): original English script (tools/sound/voices.py), spoken by the
Kokoro-82M text-to-speech model (Apache License 2.0, https://github.com/hexgrad/kokoro), packaged via
kokoro-onnx (MIT). Post-processed as command channel / field radio.

Music loops (harbor, voyage, tension, northern, triumph): original synthesis, tools/sound/music.py.
Main theme (theme.ogg, the home screen): original composition and synthesis, tools/sound/theme.py —
low brass, trumpets, taiko, a metallic anvil pulse and a synth bass on top of the same small orchestra.
No samples, no quotation of any existing score.
