so i'm not 100% sure if this is happening on the itch page or on my html page that i'm embedding, but i'm trying to get an html game to embed seamlessly into the itch page (they have the same background color). unfortunately, there's this 1px stroke around the bottom right sides of the canvas.

when i run the html project locally, there's no border. so i suspect that itch is adding this stroke or there's some problem with how i'm embedding it. any ideas?
