I wonder how much of this stuff Safari will end up having. I wouldn't be surprised if it just ends up being the same as iPads 'desktop class' browsing.

(I started this, got to a good point then thought - idiot, you didn't search to check if Steph (or anyone else) has already done this)

taking inspiration from your articles on the code to use … I've been working on a little 'test page' earlier this morning. This is Safari (desktop) 26.6 so perhaps 27 has some more details. ¯\_(ツ)_/¯

I just checked caniuse and Safari doesn't support viewport segments 🤨 They support the Visual Viewport API but not the media queries.

Nor does Safari support the Device Posture API.

Caniuse has been known to miss stuff especially if it's not in any release notes but I'm also surprised if they even parse the media queries beyond what an unknown media query does. I definitely wouldn't expect anything until at least 27 but probably would wait till 27.1 or be iOS only or something
