These are modern “Emulated Devices” (a.k.a. responsive dimensions) for Chrome DevTools’ Mobile Device Viewport Mode.
They are specifically Apple devices, subtracting for recent Safari UI (as in window.innerWidth/Height), and cleverly sorted with some dark-arts unicode shenanigans. (This glitchy, unloved portion of the tools sorts lexicographically, because of course it would.) Ergonomics!
