      "text": "Because output stays stable only when the reduced hours are absorbed by redesigning work (cutting low-value meetings, admin, and interruptions) rather than by compressing the same tasks into fewer days, the four-day week's success is contingent on work redesign and on the job being redesign-amenable - and absent that redesign the 100-80-100 model becomes a hidden productivity trap.",
