 - `--performance-mode auto` keeps conservative defaults while preserving explicit user flags.
 - If the checkpoint includes a PE component, SGLang loads it automatically with the native Ministral3 runtime. Use `--layerwise-offload-components pe` when the local PE decoder needs to trade latency for lower GPU memory usage.
 - Treat FSDP, SP/Ulysses/Ring, and TP as explicit benchmark knobs. Measure the target resolution, step count, and GPU type before making them production defaults.
