// The real binary walks an X timeline and, with `--dump-json`, prints one JSON
// metadata object per tweet to stdout. This emits a small deterministic set in
// exactly that shape so the posts pipeline (normalize → JSONL → archive) can be
// driven end-to-end WITHOUT ever touching x.com — the suite must never depend
// on X's live defenses, and no test run may risk a real account.
//
// Deterministic by design: the same tweets every run, so a re-run proves the
// incremental (no-duplicate) guarantee.
