New tts/generate_sfx.py mirrors generate.py (MOSS-TTS) but for the
MOSS-SoundEffect checkpoint: text-only ambience/SFX generation, no
reference audio or voice cloning. Needed PYTORCH_ALLOC_CONF=
expandable_segments:True baked in - this checkpoints weights alone use
~22.3GB of this boxs ~23.56GB usable VRAM, leaving generate() itself no
room without it (confirmed via OOM otherwise).
webui/app.py gets a new standalone "5. Sound effects" section in the
Pipeline Studio tab (separate from the AuK/MOSS-TTS voice flow - this is
a different generation primitive with no reference/history state).
Verified end-to-end: three real test clips (door creak, market ambience,
car pass) generated cleanly, approved by Steve as "definitely passable,"
then wired into the GUI and confirmed working through app.py itself.
