// kumiko-framework#1480 twin bug: instantToDriver referenced the global
// `Temporal` the same way instantFromDriver in bun-db/query.ts did. Fixed
// the same way — static `import { Temporal } from "temporal-polyfill"` in
// dialect.ts. This test deletes globalThis.Temporal before calling it,
// proving the write path no longer depends on the global either.
