A Solidus shipping calculator for merchants whose delivery economics fit explicit weight rules. Exact-decimal rates cover bands, parcel overflow, handling, free-shipping thresholds, and item constraints without a carrier account or network request. Invalid configuration and missing weights *fail visibly instead of generating a plausible but wrong checkout price*. The merchant owns a fast, testable pricing model that remains understandable as rates change.

*Priced locally, exactly, every time.*
