Why Presets, Not Math
The previous version of the node calculated resolution mathematically the same area for all formats. This caused glitches: with vertical formats, the long side tended to values outside the Flux2 comfort zone, and the model began to break. The previous version calculated resolution mathematically equal area for all formats. This caused artifacts: vertical formats pushed the long side beyond Flux2's comfortable generation zone, causing the model to break.
Solution: Experimental selection of presets at 10 steps.
Every value tested the model generates stably, without artifacts, without doubles.
