When greedy word-wrap leaves a 1-word last line, pull the penultimate line's tail word down so the orphan has at least 2 words. Skipped if the combined length would exceed budget (invariant takes priority over cosmetics). Visible on nested_let_rec.prose.txt: before: '...captures outer's param\n/// i.' after: '...captures outer's\n/// param i.' Two new unit tests; existing 4 snapshots unaffected (none had a 1-word orphan).
