The status line carried `whitespace-nowrap`, and once populated its content
(`min 1ms / med 2ms / avg 3ms / max 4ms`) measured 325px inside the 270px host
column at a 320px viewport. The element does not clip, so the overflow
propagated to the document and the page scrolled horizontally.
Drop `whitespace-nowrap` from the status line and instead make each
label/value/separator group individually unbreakable, so wrapping happens only
between stats and a wrapped line never starts with a separator. The line fits
on one row in the 420px desktop column, so the wide layout is unchanged.
The repeated class string is now a single constant.
