"""Live spike for the Swiftly product API (R3-0, ad-hoc admin tool).

Usage:
    python scripts/spike_swiftly_ingest.py --confirm-live

Fetches the categories page + ONE category (default ``Product/meat_seafood``)
against the live Swiftly API, prints the item count, and pretty-prints
two sample mapped products. Does NOT persist anything to Postgres — the
purpose is to verify the token + parser round-trip on demand without
running the full scrape.
