It is 2:00 on a Saturday in Hanalei. The shop is full, one person is at the register, and the phone is ringing with someone asking whether you have a medium.
A Kauaʻi shop owner behind the register cannot answer the phone. The caller orders it online from somewhere else.
A shop runs five systems at once. Here they are, applied to a storefront, with the one move in each that compounds.
