Missing styling for `var` element

[pbarney]

There is no styling for the <var> element.

Current Behavior

<var> is rendered using browser defaults.

Expected Behavior

<var> should render similar to <samp>, <code> and <kbd>.

I have detailed this thoroughly in a new thread in the Ideas discussion group here:

Idea Discussion 695: Add styling for the html VAR element, which is currently unaddressed by PicoCSS

Environment

PicoCSS version 2.1.1
