"""Dynin-Omni pipeline topology (frozen).

Stage 0: token2text  — multimodal understanding / text generation (comprehension)
Stage 1: token2image — stage-0 tokens → image latents
Stage 2: token2audio — stage-1 tokens → audio latents

All three stages run on the generation worker (``LLM_GENERATION``); the
inter-stage hand-off uses the worker-connector full-payload data plane
(``*_full_payload`` producers + ``token2text_to_token2image`` /
``token2image_to_token2audio`` consumers). Deploy knobs (devices, GPU memory,
batched tokens, connectors) live in ``vllm_omni/deploy/dynin_omni*.yaml``.
