## Functionality Comparison

### Login Flow

#### BEFORE:
```
1. User visits login page
   ↓
2. Sees dropdown with "Customer" selected
   ↓
3. Decides to login as admin → opens dropdown → selects "Administrator"
   ↓
4. Enters credentials
   ↓
5. Clicks sign in
   ↓
6. Backend validates with selected role
```

#### AFTER:
```
1. User visits login page
   ↓
2. Sees Admin button highlighted (PRIMARY)
   ↓
3. If admin: stays on Admin, enters credentials
   If customer: clicks Customer button, enters credentials
   ↓
4. Visual feedback: button changes style
   ↓
5. Enters email & password
   ↓
6. Clicks sign in
   ↓
7. Backend validates with selected role from hidden input
```

**Difference:** Visual buttons are more intuitive and show Admin as primary.

---

### Register Flow

#### BEFORE:
```
1. User visits register page
   ↓
2. Sees "Register As" dropdown
   ↓
3. Can select "Customer" OR "Admin" (mistake possible!)
   ↓
4. Fills name, email, phone, password
   ↓
5. Clicks create account
   ↓
6. Backend uses selected role (could be admin!)
   ↓
7. Account created with chosen role (security risk!)
```

#### AFTER:
```
1. User visits register page
   ↓
2. Sees "Registering as: Customer" info box
   ↓
3. No role choice (hardcoded in PHP)
   ↓
4. Fills name, email, phone, password
   ↓
5. Clicks create account
   ↓
6. Backend uses hardcoded role = 'customer'
   ↓
7. Account ALWAYS created as customer (secure!)
```

**Difference:** Admin accounts cannot be created via register (hardcoded security).
