Without a player_client, yt-dlp probes web+mweb+android+tv in sequence
for every request, multiplying API calls ~4x and triggering YouTube IP
blocks. tv_embedded exposes the full format list in one shot and is the
least restricted client for authenticated sessions.
Applies to: search, trending, video/channel metadata, playlists, subs,
comments, and downloads — every yt-dlp invocation site.
