05 · Adobe 4K ratios and pixels

Aspect ratio	Orientation	4K pixels	quality
16:9	Landscape	`3840x2160`	`medium` / `high`
9:16	Portrait	`2160x3840`	`medium` / `high`

Selection rule: For the Adobe medium group, send quality="medium"; for Adobe high, send quality="high". The current common 4K routes list 16:9 landscape and 9:16 portrait explicitly. Avoid unconfirmed oversized pixel combinations.
