Page loads instantly with song-count order, then silently re-sorts
once the backend aggregates play counts across all songs. Result cached
20 min server-side to avoid repeated full-library fetches.

Each tryYtmSearch() call made a fresh HTTP request, so YouTube could
return different result orderings between steps. The correct video
(right title, wrong channel name) appeared in step 1 but was gone by
step 3 — a worse video with matching keywords slipped through instead.
Now fetch 10 YTM URLs once upfront and filter the same list with
progressively relaxed rules. Also saves 2-4 extra YTM requests per
download.

Replaces the broken open.spotify.com/get_access_token scrape with
accounts.spotify.com/api/token (Basic auth, client_credentials grant).
Adds SPOTIFY_CLIENT_ID/SECRET to config, docker-compose, and .env.example.
Health endpoint now reports spotify.configured; frontend disables the
importer and shows a setup guide when credentials are missing.

Using the full artist name with Unicode symbols (e.g. ☆NoAki☆) in ytsearch
caused YouTube to return 0-1 completely irrelevant results, letting wrong songs
fall through to the no-filter fallback. Strip only \p{S} (Unicode symbol chars
like ☆ ★ ♥) but keep ASCII punctuation — so N!GHT stays "N!GHT" (important for
disambiguation) while ☆NoAki☆ becomes "NoAki" (searchable).
YTM URL still uses the original artist name with all chars intact.

Use mainArtist (with special chars) for ytsearch queries so e.g. "N!GHT - Yume"
searches correctly instead of "NGHT - Yume" which YouTube misreads as "night"
and returns ambience videos.

- YTM URL now uses unstripped artist name (e.g. "N!GHT" instead of "NGHT") for
better search ranking on YouTube Music
- Steps 1-2 of cascade now include a soft channel ~= filter using the artist's
first word, preventing wrong-artist songs with matching titles from being
downloaded (e.g. a different "Moonlight" for N!GHT)
- Steps 3+ drop the channel filter so label-hosted tracks still get found

- ytdlp.js: use \b word boundaries in all variant filter regexes so that
partial matches like "nightcoreals" containing "nightcore" no longer
falsely reject official videos; also fixes sped regression (!~= \bsped\b
instead of the too-narrow "sped up" pattern)
- squid.js: restructure verify payload to mirror challenge response layout
{ parameters, solution: { number, derivedKey }, signature }

- squid.js: add top-level signature from challenge response to verify payload
(server added signature validation, causing HTTP 400 without it)
- ytdlp.js: switch variant filter from !*= to !~= (?i) so Remix/REMIX/remix
are all rejected, not just lowercase

- ytdlp.js: watch for [youtube:tab] in yt-dlp output during flat-playlist step;
return [] when channel expansion is detected so cascade falls through to ytsearch
- Revert player.js / main.js / state.js PWA _changingTrack changes (not effective)

The /api/altcha/challenge response is { parameters: { nonce, salt, ... } }.
Destructuring the top level left nonce/salt/keyPrefix as undefined, causing
Buffer.from(undefined) crash on every squid.wtf download attempt.

--match-filter 'webpage_url !*= /browse/' was applied to individual videos
AFTER yt-dlp expanded an artist channel into its uploads playlist — by then
each video had a /watch?v= URL, so the filter never fired.
New approach: run yt-dlp --flat-playlist --print webpage_url first to get
the raw search result URLs, filter /browse/ entries in Node.js, then pass
only the actual watch?v= video URLs to yt-dlp for download with --max-downloads 1.
The channel is never expanded; we get the real song from the search results.
