`SxCP Krea2 Resolution Selector` outputs model-friendly `width`, `height`,
`resolution`, aspect ratio, megapixel, and hosted API fields for Krea2. Use
`profile=turbo_local_2k` for local Turbo generation up to a 2K long edge, or
`profile=raw_local_1k` for RAW/local 1K limits. `profile=api_hosted_1k` keeps
the official API fields visible: `api_aspect_ratio` and `api_resolution=1K`.
The node searches for the best multiple-of-16 size for the selected aspect ratio
and megapixel preset, then clamps to the selected profile's limit. Use
`max_for_aspect` to get the highest valid size for that aspect ratio, or
`random_1_to_limit` with a seed config for reproducible random sizes.
`SxCP Krea2 Resolution Selector` is a simple size picker: choose `megapixels`
and `aspect_ratio`, then use the output `width` and `height`. It assumes local
Krea2 Turbo 2K limits, searches for the best multiple-of-16 size, and clamps the
selected megapixel target when that aspect ratio cannot fit it. `max_for_aspect`
returns the largest valid size for the chosen ratio. The official Krea API
aspect ratios are listed first, with a few local helper ratios such as `8:9`
after them.
`SxCP Camera Control` and `SxCP Camera Orbit Control` output `camera_config`,
which can be connected to the prompt builder or the Insta/OF pair node. They
