Summary

• Reduced MAX_ARTWORK_SIZE from 480px to 300px in PlaybackService.kt
• Notifications and lock screen only display small thumbnails, so 300px is more than sufficient
• The UI loads artwork independently via URL, so in-app display quality is unaffected
• Reduces memory usage for the JPEG-compressed artworkData stored in MetadataForwardingPlayer

Test plan

• Verify notification artwork still displays correctly on phone lock screen
• Verify Android Auto artwork renders properly
• Confirm in-app album art is still full resolution
• Check memory usage is reduced when artwork is present
