			Companion of <code>TimeField</code> for time ranges
			(<code>{`{ start, end }`}</code>). Two endpoint inputs share
			one Label and the same Segment component; soma's
			TimeRangeField provider creates a separate TimeField context per
			endpoint so segment editing routes to the correct boundary.
			Visual chrome is reused 1:1 from <code>time-field.css</code> —
			the eidos root overlays <code>data-time-field</code> on top of
			<code>data-time-range-field</code> so the entire size / variant /
			color cascade applies inside the range without recipe
			duplication. This recipe only adds the
			<code>1fr · auto · 1fr</code> grid layout + em-dash separator.
