Correcting my earlier 'YouTube caps at ~200' claim — that's the ANONYMOUS ceiling.
YouTube throttles unauthenticated playlist extraction to ~100 (yt-dlp) / ~200
(InnerTube); ytdl-sub gets everything because it runs with browser cookies. Our
code already wires cookiesfrombrowser via youtube.cookies_browser (same as the
music client) — it's just unset. The detail endpoint now resolves with a high
limit so a cookie-authenticated yt-dlp pages the WHOLE playlist, and uses whichever
source (yt-dlp vs InnerTube) returned more, with the true header count. The partial
note now tells you to add cookies in Settings to load the full list.
