+Feature: Christmas Light Configuration
+  As a competitive resident
+  I want to follow Santa's light instructions
+  In order to win the holiday decoration contest
+
+  Background:
+    Given I have a 1000x1000 grid of lights
+    And all lights are initially turned off
+
+  Scenario Outline: Execute different lighting commands
+    When I execute the command "<command>" from <x1>,<y1> through <x2>,<y2>
+    Then I should see <result> lights turned on
+
+    Examples:
+      | command  | x1  | y1  | x2  | y2  | result  |
+      | turn on  | 0   | 0   | 999 | 999 | 1000000 |
+      | toggle   | 0   | 0   | 999 | 0   | 1000    |
+      | turn off | 499 | 499 | 500 | 500 | 0       |
+
+  Scenario: Process multiple instructions
+    When I execute the following commands:
+      | command  | x1  | y1  | x2  | y2  |
+      | turn on  | 0   | 0   | 999 | 999 |
+      | toggle   | 0   | 0   | 999 | 0   |
+      | turn off | 499 | 499 | 500 | 500 |
+    Then the total number of lights turned on should be correct
+
+  Rules:
+    - Coordinates range from 0 to 999 in each direction
+    - Coordinates are inclusive
+    - "turn on" turns on all lights in the specified range
+    - "turn off" turns off all lights in the specified range
+    - "toggle" switches the state of all lights in the specified range
