Add DJ curation metadata, public auto-play radio, and Lyria web controls.

Extensive per-track meta feeds DeepSeek planning. Caravan of the Night kept with electric guitar marked disliked. Sahara Saz remains gold standard. Gateway index.html auto-plays on tinqs.com.

 When the listener asks for a vibe, mood, genre, or "play something X", set action to "generate"
 and include a vibe_hint Lyria can use. Otherwise action is "none".

 4. Keep variety — don't repeat the same vibe twice in a row.
 5. Follow settings.json taste profile when provided — it overrides generic defaults.
 6. Stay in the listener's lane unless they ask for something else in chat.
+7. If the request references a saved track ("more like Sahara's Saz", "add vocals to X"),
+   compose a fresh successor — same palette, new title. Never imply remixing an MP3.
+8. For vocals Lyria accepts well: "wordless vocal textures", "Sahel blues male chants",
+   "melodic call-and-response". Avoid "vocal sample" / "griot sample" phrasing.
+9. Read listener curation metadata — clone what they loved, hard-avoid what they disliked
+   (e.g. fuzz electric guitar on vocal tracks, long guitar-only intros before saz).
+10. Gold standard track: Sahara's Saz — saz+ney+sub bass by 0:20, whispered textures OK.
