"Pretty simple" workflow,

Please, read nodes, they have some hints, then you can delete then

All control is carried out through the bypass nodes (at the left), for more fine tuning, you can use nodes within groups.

Upscale can be done with or without a model

In I2I route image have preset sizes for mobile 5:8 and desktop 16:9. Control through group "Latent"

After T2I image size: mobile - 800x1280 (WXGA), desktop - 1280x720 (720p)

After I2I image size: mobile -1200x1920 (WUXGA), desktop - 1920x1080 (1080p)

After Ultimate SD image size: mobile - 1600x2560(WQXGA), desktop - 2560x1440 (2K)

For iterative route change upscale factor in its group (lower then 1 will downscale)

You can change the type of detailer by changing DetectorProvider

Use daemon carefully, if you don't know what it is, just don't touch :)
