[Scenario] The image shows a maze with black walls and white paths. The green circle is the agent's starting position. Several coloured diamonds mark keys and the corresponding hollow coloured squares mark doors. Each key matches the door of the same colour.
[Rules]
1. The agent must first walk through the maze to the Red key cell to collect it (the key then disappears).
2. After collecting the Red key, the agent must walk to the Red door cell.
3. The agent may only move along white path cells; it cannot cross black walls.
[Task] The agent collects the Red key and then reaches the matching Red door. The camera is fixed; the maze layout, keys, and doors do not change. Only modify what the task requires; keep the background and any other element unchanged. Output two images: the first showing the path from start to the key drawn as a yellow line, the second showing the path from the key to the door drawn as a yellow line.
