| """Opt-in, single-request Meta Muse Glimmer via NVIDIA's NIM trial endpoint. |

| Different from billed Meta Platforms Model API. Runs ONLY when explicitly |
| enabled. Never logs authorization headers, private reasoning or response bodies |

| |
| Muse Glimmer is a reasoning model: reasoning consumes max_tokens and a short |
| budget can return empty final content even with HTTP 200. |
