- VM 210: correct SSH path, add llava:7b vision model
- Add Arc Reactor section (service, logs, SETUP button, vision cascade)
- JARVIS AI tiers: llama3.2 → llama3.1:8b, add vision tier
- Backup Systems: add JARVIS database backup (path, format, retention)

 **JARVIS uses this as Tier 1 AI** — if Ollama is down, falls back to Groq (cloud).
+**Vision cascade:** Arc Reactor calls Claude first; if Claude credits depleted, falls back to llava:7b via Ollama.
+Vision is enabled via: `/etc/systemd/system/jarvis-arc.service.d/vision.conf` → `OLLAMA_VISION_MODEL=llava:7b`
