 **Additional Default Notes:**
 - **VLM Input Sizes:** For most presets, `vlm_max_size` and `vlm_min_size` are set to `-1`, meaning the values are model-dependent and handled automatically. In `area` mode they represent pixel area; in `longest_side` mode they represent a side length in pixels.
 - **VAE Input Size:** `vae_input_max_pixels` defaults to $1024 \times 1024$ pixels (`1048576`).
+- **VAE Geometry:** `resize_vae_to_target` defaults to `true` for Mage-Flow and LLaDA-Image. Fibo enables `resize_single_ref_to_target`, `vae_size_buckets`, and `vae_center_crop`. These options are otherwise `false`. Bucket dimensions use the model's alignment (normally 16, Qwen Image 32), with a minimum side of four alignment units; if no bucket fits, output dimensions are used.
+- **Shared Encoder Input:** `vlm_use_vae_input` defaults to `true` for Fibo and Qwen Image 2.1, otherwise `false`. All these options can be overridden individually after selecting a preset.
