• Caching - Data cached locally with AsyncStorage for offline access
• Best Mandi Selection - Algorithm finds highest price for maximum farmer income
• Trend Analysis - Shows price movement direction
• Refresh Logic - Fetches latest data when online, uses cache when offline

For each scheme:
  1. Check land size → Within limits?
  2. Check state → Available in farmer's state?
  3. Check category → Farmer qualifies by category?
  4. Check documents → Has Aadhaar? Bank account?
  5. Check other criteria
  
  Result:
    ✅ All criteria met → ELIGIBLE
    ❌ Missing requirements → NOT ELIGIBLE (show missing items)
    ⚠️ Some criteria met → PARTIALLY ELIGIBLE (show progress)

• PM Kisan - Direct income support
• Crop Insurance - Pradhan Mantri Fasal Bima Yojana
• Irrigation - Pradhan Mantri Krishi Sinchayee Yojana
• Fertilizer Subsidy - Soil health & nutrients
• Seed Programs - Quality seed distribution
• Training Programs - Skill development

Recommended Water = 
  Base Amount × (Soil Moisture Factor) × (Crop Type Factor) × (Season Factor)

Water Savings % = 
  (Standard Water - Recommended Water) / Standard Water × 100

Cost Saved = Water Savings % × Water Bill Rate

Wheat: 0.8x (Lower water requirement)
Rice: 1.5x (Higher water requirement)
Cotton: 1.2x (Moderate-high water requirement)
Sugarcane: 1.4x (High water requirement)

1. Scan - Take photo of affected crop area
2. Analyze - AI identifies potential diseases
3. Diagnose - Confirms disease with confidence score
4. Recommend - Provides treatment options
5. Track - Monitors recovery progress

User: "क्या मैं सरकारी योजना के लिए पात्र हूं?"
App: Records voice → Detects intent "CHECK_ELIGIBILITY"
    → Loads farmer profile → Checks all schemes
    → Displays eligible schemes with benefits

User: "गेहूं का भाव क्या है?"
App: Records voice → Detects "CROP_PRICE" intent
    → Extracts crop "Wheat" → Fetches mandi prices
    → Speaks: "गेहूं की सर्वोत्तम कीमत जालंधर मंडी में ₹2,200 है"
    → Shows all mandis with prices

User: "मेरी गेहूं को कितना पानी चाहिए?"
App: Records voice → Detects "SHOW_IRRIGATION" intent
    → Gets current crop data → Calculates water needs
    → Shows: "मिट्टी की नमी देखते हुए 5,000 लीटर पानी दें"
    → Highlights water savings (30% vs standard)
