SubSonicSter is a Hitster-compatible card game app that uses SubSonic-compatible music servers for playback.

Features:
• QR code scanning for Hitster game cards
• CSV-based song mapping for different card sets
• SubSonic API integration for music search and streaming
• Audio playback with buffering using ExoPlayer
• Card set configuration and availability checking
• Modern Material Design 3 UI with Jetpack Compose

Requirements:
• A SubSonic-compatible music server (e.g., Navidrome, Airsonic, Gonic)
• CSV files mapping QR codes to songs (available at https://github.com/andygruber/songseeker-hitster-playlists)
• Hitster game cards with QR codes

How It Works:
1. Configure your SubSonic server connection
