+  Import the openModal function to handle showing login popups/modals
+  Import the base API URL from the config file
+  Define constants for the admin and doctor login API endpoints using the base URL
+
+  Use the window.onload event to ensure DOM elements are available after page load
+  Inside this function:
+    - Select the "adminLogin" and "doctorLogin" buttons using getElementById
+    - If the admin login button exists:
+        - Add a click event listener that calls openModal('adminLogin') to show the admin login modal
+    - If the doctor login button exists:
+        - Add a click event listener that calls openModal('doctorLogin') to show the doctor login modal
+
+
+  Define a function named adminLoginHandler on the global window object
+  This function will be triggered when the admin submits their login credentials
+
+  Step 1: Get the entered username and password from the input fields
+  Step 2: Create an admin object with these credentials
+
+  Step 3: Use fetch() to send a POST request to the ADMIN_API endpoint
+    - Set method to POST
+    - Add headers with 'Content-Type: application/json'
+    - Convert the admin object to JSON and send in the body
+
+  Step 4: If the response is successful:
+    - Parse the JSON response to get the token
+    - Store the token in localStorage
+    - Call selectRole('admin') to proceed with admin-specific behavior
+
+  Step 5: If login fails or credentials are invalid:
+    - Show an alert with an error message
+
+  Step 6: Wrap everything in a try-catch to handle network or server errors
+    - Show a generic error message if something goes wrong
+
+
+  Define a function named doctorLoginHandler on the global window object
+  This function will be triggered when a doctor submits their login credentials
+
+  Step 1: Get the entered email and password from the input fields
+  Step 2: Create a doctor object with these credentials
+
+  Step 3: Use fetch() to send a POST request to the DOCTOR_API endpoint
+    - Include headers and request body similar to admin login
+
+  Step 4: If login is successful:
+    - Parse the JSON response to get the token
+    - Store the token in localStorage
+    - Call selectRole('doctor') to proceed with doctor-specific behavior
+
+  Step 5: If login fails:
+    - Show an alert for invalid credentials
+
+  Step 6: Wrap in a try-catch block to handle errors gracefully
+    - Log the error to the console
+    - Show a generic error message
