 - Lets you choose an `aspect_ratio` and resolution quality tier
 - Outputs `INT` values: `width`, `height`
 - Optional `IMAGE` input auto-matches the closest supported aspect ratio as an override
+- Optional `round_to_16` snaps output to dimensions divisible by 16 while staying close to the target ratio
 - Keeps equivalent quality tier when you switch aspect ratios in the UI

 ## Usage
 
-1. Add the `Wan Resolution` node.

 2. Pick `aspect_ratio` and `resolution`.
-3. Optional: connect an `IMAGE` input to auto-select the nearest aspect ratio.
