Mobile Menu JavaScript and Scroll Behavior | Project Part 6

In this live stream, I wire up the responsive header interactions for the Practice Layouts homepage. We create a navigation module, toggle the mobile drawer with a body class, update `aria-expanded`, and add Escape key support so the menu can be closed from the keyboard. Then we create a scroll module and use `matchMedia` so the scroll behavior only applies on mobile. The goal is to hide the mobile filter/search form after the user scrolls, but the stream also shows a real layout limitation caused by the current header structure. This is a good one if you want to see vanilla JavaScript, CSS state classes, and responsive UI problem solving in the same session.
