One control, three values, horizontal only — Mobile, Tablet, Desktop on one row, smallest first because
that is the direction they cascade.
Not tied to the device toggle, and the difference from the per-band control is the reason. That one has
two axes and three bands, where showing every width would be eighteen inputs, so it writes to whichever
width the preview is showing. Here there is one axis and one value, so all three fit — and seeing them
together is the point. A gutter is a progression, 4 then 8 then 12, judged as a whole; reading it off
three separate visits to the same control is how a site ends up tighter on a tablet than on a phone.
Inherit still says what it is inheriting, and Mobile still says "None", because there is nothing below
it to inherit from.
