Start at https://adaptivecards.io/ with the system dark theme enabled, then navigate the complete site using the Edge Dev browser and Tab key as described. Compare the page and Adaptive Cards with the expected dark-theme appearance; done means backgrounds, text, and UI elements consistently adapt across the site.
