## App
- Engine key: `qwen21` · UI label: **Qwen 2.1**
- Generate (T2I) only in this build. Edit / Compose / Iterate / Video disable with: “Qwen 2.1 is T2I in this build”.
- Sampler defaults: euler / simple / cfg **1** / steps **25** · `ModelSamplingAuraFlow` shift **3.1**
- Default canvas **1024×1024** (aspect 16:9 / 9:16 / 1:1 → long-edge square via `TextEncodeQwenImage21` resolution; multiples of 32). Drop to 768 if VRAM errors.
- **Generate** (T2I) and **Edit** (same checkpoint, second graph). Compose / Iterate / Video / Extend / Music stay disabled unless a graph exists.
- Edit requires Start still → `images.image_1`; prompt slots use `<image1>` / `<image2>`. If the user omits `<image1>`, the runner prepends `Keep the subject in <image1>.`
- Face / outfit locks stay Klein semantics — they do not drive Qwen slots.
- Sampler defaults: euler / simple / cfg **1** / steps **25**. Edit uses `QwenImage21Cache` (device auto, dtype int8). T2I uses `ModelSamplingAuraFlow` shift **3.1**.
- Default canvas **1024×1024** (aspect 16:9 / 9:16 / 1:1 → long-edge ~1024 via `TextEncodeQwenImage21` resolution; multiples of 32). Edit with aspect `auto` follows `image_1` aspect at ~1024.
- No hero / locks / Klein LoRA stack on this engine.
