<Note>
  Models may be available in multiple regions. SLNG auto-selects the closest region by default. Use the `X-Region-Override` header to pin a specific region, or `X-World-Part-Override` to pin a broader geographic zone (`na`, `eu`, `ap`). See [Region & World-Part Overrides](/region-override) for details.
