/**
 * Built-in playlist-item normalizer — accepts the v1 / NoMercy server wire

 * and idempotently: canonical input passes through untouched. Wired into the
 * kit's queue ingest pipeline via `normalizePlaylistItem`, so consumers hand
 * `setup({ playlist })` the raw server payload — exactly like v1 / JW /
 * video.js — and never reshape items themselves. App-specific concerns go in
 * the `transformPlaylistItem` config callback instead.
