    HTTP method (default GET); the zip reader's length fallback sends HEAD.

    headers?: HeadersInit
    onExhausted?: (error: unknown) => void
    lane?: FetchLane
    cache?: RequestCache

    HTTP cache mode for the request. The zip range reader passes no-store: with the default mode Chrome serialises same-URL Range GETs through its HTTP-cache writer lock, which held a hosted archive at two reads in flight.

    Gate priority class (default demand), or a cell a coalescing caller may raise while the request is queued. See utils/fetch-concurrency.ts.
