Album art placeholders now show a treble clef (Rin's signature)
instead of generic icons. Applied to all three locations:
- Gallery ribbon: small treble clef (5x5)
- Gallery tile: medium treble clef (10x10)
- DetailPanel: large treble clef (14x14) with 'No album art' label
The Lyria API returns a candidates[].content.parts[] array where:
- parts[0] = text metadata (e.g. '<instrumental>')
- parts[1] = inlineData with the actual audio payload
Previous code only checked parts[0] for inlineData, which always failed
with 'No audio data in response'. Fixed by iterating all parts to find
the inlineData entry.
Successfully generated first real audio clip (lo-fi hip hop, 30s, 728KB MP3).
Also includes: .env.example, requirements updates, docker-compose fixes,
frontend vite config, logger setup.
