Frozen Food Shipment Tracker

Yes, more than intuition suggests: surface thawing during a power gap or long door-open refreezes into ice crystals that wreck texture, and repeated micro-cycles compound. The standard is the chain held at -18 °C throughout, not 'it was frozen at delivery'. Track power custody at each milestone and treat any gap longer than minutes as a logged event with the QA team's name on it.

The constraint encoded in the setpoint / tolerance field: frozen tolerates brief upward drift less than people assume. Generic trackers show where freight is; cargo-specific tracking shows whether the plan still works for what this freight IS — and that difference is where the expensive mistakes hide.

At the cargo's own tempo, not the carrier's reporting cycle. Frozen Food Shipments set their cadence by their risk clock — for time-critical variants that means same-day (sometimes same-hour) updates around the vulnerable milestones, relaxing only where the cargo genuinely can wait. A stale status on this board is a decision being made blind somewhere downstream.

No — storage is local to your device (localStorage), nothing uploads, which suits the commercially sensitive details this cargo type involves. Use CSV export deliberately when sharing is the point: claim files, customer reports, team handoffs. Private by default, shareable on purpose.
