Hey @gmajoulet, @newmuis! These files were changed:

extensions/amp-story/1.0/amp-story-system-layer.css

High level question: why don't we want the new one-panel desktop to be [desktop]? Similar to #35772 where we add the layout to the list of desktop layouts.

#35772 had no side effects and only effected that one line. The desktop attribute will be cleaned up as much as possible once we're ready.

Adding desktop here causes visual side effects like chunkier SVGs with different margins.

Got it, so eventually we want to bring back the desktop attribute, but for now it would introduce back some of the styles we're trying to get rid of?

It would make more sense for our UI naming conventions to be based on aspect ratio rather than device type.
I do not think we should bring back desktop. Once we clean up all the unused desktop code I think we'll be able to scope a name change more easily and decide if we want to do that.

Do any of the other locations that use [desktop] also need this? Still LGTM since this is the only rule we know it's been affected.

They do not appear to and will be removed during cleanup.
