Lyrics Card Generator v5.2.1 Release Notes

Song link parsing restored

v5.2.1 restores real song-link parsing for Spotify, Apple Music, NetEase Cloud Music, and QQ Music while preserving the network hardening introduced in v5.1.0 and v5.2.0.

Numeric QQ Music songDetail links now use songid and correctly populate the title, artist, album, and cover.
NetEase JSON requests negotiate the correct response type and once again return complete song, artist, and album metadata.
Apple Music uses the original track ID even when the page redirects home, then returns a valid track URL.
Spotify track links remain compatible, and all four platforms are covered by live-link regression assertions.

Security and compatibility

Per-hop URL/DNS validation, redirect revalidation, response size and type limits, and multi-address IPv6/IPv4 fallback remain enabled.
Lyric-card output, project data formats, and the existing visual direction are unchanged.
Windows x64 Setup and portable artifacts have been rebuilt for v5.2.1.
