//
// Third write capability, and the highest-blast-radius one: a single press can
// dispatch dozens of riders. Everything here is built around making that
// visible BEFORE it happens and legible AFTER.
//
// Shared with the single-order path on purpose:
//   • buildOrderPayload — so a bulk row and a single order are byte-identical
//     on the wire, including the pickuplocationid workaround (that field 500s
//     server-side; raw pickup fields are sent instead).
//   • validateOrderDraft — the same gate, applied per row.

// Server cap, documented in express-console-api.md. Exceeding it is a hard
// error rather than a silent truncation, so rows are chunked instead.

// dropped line — a bulk import that quietly skips row 14 is worse than one
// that refuses.
