CookiesFrom so whitespace-only values are treated as unset, matching
NewCookieProviders trimming behavior. Normalize CookiesFrom during loading or
consistently apply strings.TrimSpace to every relevant decision, and add a test
covering a whitespace-only cookies_from value.

the documentation by adding a blank line immediately before and after the fenced
TOML example, preserving the example content and surrounding text.
In `@external/ytmusic/cookie_provider.go`:
- Around line 166-170: Remove the resolver-global cookie mutation from
NewCookieProviders and carry each provider’s cookie source through its playlist,
search, and playback invocation paths. Update the relevant provider methods and
yt-dlp calls to use their instance-specific source, ensuring different
authenticated providers do not overwrite or reuse one another’s cookies.
In `@resolve/ytdl_playlists.go`:
- Line 99: Update parseYTDLPlaylistFeed to wrap scanner.Err() with contextual
fmt.Errorf and %w; update FetchUserPlaylists to wrap exec.LookPath and
cmd.Output errors, remove user-facing installation guidance from this resolver
package, and move that guidance to run or main.go while preserving the
underlying errors for callers.
In `@site/index.html`:
- Line 721: Update the YouTube provider card in the site content to document
both YouTube and YouTube Music, including Liked Videos and Liked Music, while
preserving the existing cookie-based authentication contract and cookies_from
configuration reference. Keep the corresponding user-visible provider
documentation synchronized with this change.

Pull request overview
Adds a cookie-backed “zero OAuth” path for YouTube/YouTube Music so users can browse/play their library playlists (including Liked Music/Videos) using yt-dlp --cookies-from-browser, while keeping the existing OAuth-based provider available.
Changes:
- Introduces cookie-backed YT/YT Music providers and a
yt-dlp-based playlist feed scraper (/feed/playlists) with parsing + caching. - Updates app wiring to choose OAuth providers when credentials exist, otherwise fall back to cookie providers when
cookies_fromis configured. - Updates setup wizard + docs + site copy to document the cookie-based setup flow and refresh behavior.

- In KindAll, the pinned LM/LL entries also drop the TrackCount even though it can be read from the scraped feed. Keeping the counts improves the provider list display consistency with the OAuth-backed providers.

- Line 118: Update the playlist classification and cookie-authentication
documentation to state that cookie-backed providers append every custom playlist
to both Music and Video results, do not classify playlists by YouTube category,
and do not populate ytmusic_classification.json; retain cache and
reclassification guidance only where it applies.
In `@external/ytmusic/cookie_provider.go`:
- Around line 84-86: Wrap the resolver errors returned by fn(b.browser) with
fmt.Errorf using %w and a clear provider-operation context. Apply the same
contextual wrapping to the corresponding error returns around lines 126–129 and
302, distinguishing playlist fetch, playlist-track resolution, and search
operations while preserving the existing control flow.
Apply the same fix in `@resolve/ytdl_playlists.go` around lines 99 - 139.
- Around line 104-107: Serialize saveSnapshot calls in the snapshot update flow
around dc.snapshot(), using the existing mutex or a dedicated write lock so
concurrent playlist, track, and refresh operations cannot overwrite newer cache
state with stale snapshots; alternatively, add version validation and discard
stale snapshots before writing.
In `@main.go`:
- Around line 151-152: Replace the player-global cookie mutation in the YouTube
setup around SetYTDLCookiesFrom with provider- or track-scoped cookie-source
storage, and select that source when constructing each provider-specific yt-dlp
invocation. Preserve independent SoundCloud, NetEase, and YouTube cookie
configurations without allowing one provider’s setup to overwrite another’s.
Apply the same fix in `@external/ytmusic/cookie_provider.go` around lines 169 -
