tests can freely rely on these assumptions being true:
* The device is a full-color device.
- * The device has a viewport width of at least 800px.
+ * The device has viewport dimensions of at least 800px by 600px.
* The UA imposes no minimum font size.
* The `medium` `font-size` computes to 16px.
* The canvas background is `white`.
