How shortages ripple through supply chains

At 0:10–1:01, an obvious trigger gives way to a deeper causal question; the dated shop example at 1:01 makes that abstract question concrete. Maps and port footage connect the shop to the bottleneck at 2:22, while figures at 3:29–4:16 and the accelerating constraint chain at 5:19–5:38 turn the explanation into a legible feedback loop. The 5:44–5:56 replay peak aligns with the handoff to a second shortage example, though that alignment alone does not prove why viewers replayed it.
