🚀 Vectro+ Interactive Demo
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Step 1: Creating sample embeddings...
✓ Created 16 semantic embeddings (fruits 🍎, vehicles 🚗, colors 🔴)

Step 2: Streaming compression...
✓ Created dataset.bin (VECTRO+STREAM1 format)

Step 3: Quantization (size reduction)...
✓ Created dataset_q.bin (QSTREAM1 format)
💾 Space savings: 75%

Step 4: Semantic search...
Query: Searching for fruits 🍎
  → 1. 🍎 apple -> 1.000000
  → 2. 🍊 orange -> 0.987234
  → 3. 🍌 banana -> 0.956789

Step 5: Interactive web UI...
🚀 Server starting on http://localhost:8080
📊 Dashboard with real-time metrics
🔍 Search interface with instant results
