Landing page captured for the 2026-11-09 issue.

Field notes

The page puts white-screen controls alongside linked color screens and display checks. Users can adjust warmth from 2,000 K to 9,000 K, set a shutoff timer, request that the browser keep the display awake, and download PNGs in several listed resolutions and device sizes. The page says the tools run in-browser without sign-up or installation; its iPhone note cautions that Safari cannot hide the toolbar on a web page.
