the problem

A narrow window is not a phone.

A narrow browser window is not a phone. Sites branch on touch, on the user agent and on device pixel ratio, so a squeezed desktop layout looks like a mobile bug that is not there — and the emoji are wrong on both.

the answer

A preset is a whole device.

A preset is a whole device: viewport, scale, touch, user agent, and the emoji set that device would actually render. Change one parameter to change the device.

// the call
{
  "url": "https://example.com",
  "preset": "iphone",
  "color_scheme": "dark"
}

preset: "iphone"

Presets are frozen by name. iphone will not quietly become a newer model and change everybody's webshots.
