 22  
 23  ### Step 1: Open Browser
 24  Navigate to:
 25  ```
 26  http://77.90.13.121:9753
 27  ```
 28  
 29  ### Step 2: You Should See
 30  - **Title**: "COMPOSABLE SCAN" at the top
 31  - **Toggle Button**: Green button labeled `[MAINNET]` with network stats
 32  - **Search Box**: Below the stats
 33  
 34  ### Step 3: Click the Toggle
 35  1. **Find the green button** that says `[MAINNET]`
 36  2. **Click it** - it will change to orange `[TESTNET]`
 37  3. **Watch** the block number update (different network)
 38  4. **Notice** the color change (green → orange)
 39  
 40  ### Step 4: Switch Back
 41  1. **Click the orange** `[TESTNET]` button
 42  2. **Watch** it change back to green `[MAINNET]`
 43  3. **See** the block number update again
 44  
 45  ### Step 5: Test Persistence
 46  1. Switch to testnet (orange)
 47  2. **Reload the page** (F5 or Ctrl+R)
 48  3. **Verify** it stays on testnet (still orange)
 49  4. This proves localStorage is working!
