 it as a memory option, not as an INT8 throughput claim. The embedded Quanto map
 is the selector; adding `--quantization` would describe a different operation.
 
+Qwen3-VL GGUF files use the same component option:

+```bash Overlay
+--component-paths.text_encoder \
+  DeepBeepMeep/MiniMax-H3/Qwen3-VL-32B-Instruct/qwen3vl-32B-MiniMax-H3-Q4_K_M.gguf

+The file selects its own Q4/Q6 layout; do not add `--quantization`. SGLang keeps
+the aligned vocabulary table and language linears in packed GGML storage. The
+smaller Comfy vision tower, whose flattened blocks can cross row and TP shard
+boundaries, is restored one matrix at a time to BF16 during loading.
+This CUDA-only memory option supports encoder TP and layerwise placement, but
+not encoder FSDP. Like the Quanto variant, it is approximate and is not a
+throughput claim.
