Re: [indie-ui-context] boolean media queries should probably use 1/0 values, not on/off

It was also recommended to switch the false value to “none” instead of “off” and that anything else was “truthy” which would allow the shorthand syntax. 

Is there a preference for 0 over none? As Tab mentioned, boolean media queries have a way of not remaining boolean.
