      Only when there is one, and `trim()` because a blank string is not one. Most
      stages carry no description, and an element emitted unconditionally is an
      empty flex item holding the chip's gap open on its trailing edge — a chip
      wider than its own text. A whitespace-only value looks identical on screen
      and is truthy, so a bare `@if` would let exactly that case back through.
      Dropping the node is what the stylesheet's `:nth-child(2)` description rule
      expects; see the note there.
