description:
"force-dynamic disables static + ISR rendering. The route runs the function on every request. Sometimes necessary (cookies, headers, real-time data), often a habit that costs function-duration and edge-requests at scale.",
fix:
"Audit the route. If dynamic behavior comes from cookies()/headers()/searchParams, force-dynamic may be redundant — Next infers dynamic automatically. Consider revalidate / 'use cache' / generateStaticParams if any portion can be pre-rendered.",
