Deep caller personality: named people, memories, vehicles, opinions, arcs

- Named relationships (20M/20F): "my buddy Ray", "my wife Linda" — not generic
- Relationship status with detail: "married 15 years, second marriage"
- Vehicle they drive: rural southwest flavor (F-150s, Tacomas, old Broncos)
- What they were doing before calling: grounds call in a physical moment
- Specific memory/story to reference: flash floods, poker wins, desert nights
- Food/drink right now: Tecate on the porch, third cup of coffee
- Strong random opinions: speed limits, green chile, desert philosophy
- Contradictions/secrets: tough guy who cries at TV, reads physics at work
- Verbal fingerprints: 2 specific phrases per caller
- Emotional arcs: mood shifts during the call
- Show relationship: first-timer, regular, skeptic, reactive
- Late-night reasons: why they're awake
- Topic drift tendencies for some callers
- Regional speech patterns in prompt (over in, down the road, out here)
- Opening line variety based on personality
- Local town news enrichment via SearXNG
- Ad channel now configurable in settings UI
