[Proposal] Lightweight "Social Bridge" Features (Universal Links, Image Sharing, QR)

[YisusPineapple]

Context
Users often feel trapped in walled gardens like Spotify, YouTube Music, or Apple Music, not because of quality, but due to social friction: they can't easily share music with friends using other apps.

As a privacy-first FOSS project, we don't want to build a closed ecosystem. Instead, we can implement lightweight, serverless tools to break down these barriers and make ArchiveTune a universal hub.

I propose 3 features. Please let me know which, if any, align with the project's vision.

1. Universal Link Sharing (Interoperability)

Concept: When sharing a track, auto-generate a universal link using services like Odesli (song.link).
Flow: The app takes metadata -> generates song.link/youtube/VIDEO_ID -> the recipient chooses to open it in their app (Spotify, Apple Music, etc.).
Key Benefit: Turns ArchiveTune into a neutral hub that facilitates music sharing with any user, on any platform.

2. "Now Playing" Card Generator (Visuals)

Concept: A button to render the "Now Playing" view (Album Art + Title + Colors) into a static PNG image (9:16) for sharing on social media Stories.
Benefit: Gives users the visual sharing power of Spotify, but generated 100% locally on the device, respecting privacy.

3. Offline Playlist QR (Local P2P)

Concept: Share a playlist with a nearby friend without internet.
Implementation: Compress the playlist's tracklist into a JSON string, display it as a QR Code. The other device scans it to rebuild the playlist.
Benefit: True offline, peer-to-peer social interaction.

These features would make ArchiveTune a powerful "social bridge" in the music app world, strengthening its FOSS values without adding bloat or server costs.
