You're right, and I edited my comment accordingly, but I asked Google and got this interesting AI response, so I guess a lot of people on the internet make the same mistake, since AI just echos its training data:
The term "Continental United States" (CONUS) generally refers to the 48 contiguous states plus the District of Columbia, excluding Alaska and Hawaii. It encompasses the landmass of the United States located on the North American continent. While sometimes confused with the "contiguous United States," which also refers to the 48 states, "continental" specifically emphasizes the geographical location on the continent.
