/**
 * Contract tests for the 4gray/iptv-playlist-parser fork (jest maps the
 * module to the real parser source via test-stubs/iptv-playlist-parser.mjs).
 * Guards the fork-specific behaviors iptvnator depends on:
 * - no URL length/format validation (issue #1189: Pluto JWT URLs > 2084 chars)
 * - '#' comments never become URLs and never shift the item index
 * - the fork-only `radio` attribute survives upstream syncs
 * - `url` is stripped at the first '|' while pipe params land in `http.*`
