- **Example:** `APP-20260113-00001`
- **Generated Automatically:** On application submission
- **Used For:** Follow-up tracking without login

### 2. Public Routes (No Authentication Required)

|-------|-----|--------|---------|
| `application.create-public` | `/apply` | GET | Show public application form |
| `application.store-public` | `/apply` | POST | Submit public application |
| `application.reference` | `/application/{reference_number}` | GET | Check status by reference number |

### 3. Public Views

- Added `storePublic()` - Process public application submissions

### 6. Navigation Updates
