-The Actions surface crops the launcher’s full-size background at its own position, keeping the glows continuous without showing the results underneath.
+Action and provider popups paint a popup-sized background using the launcher window’s gradient coordinates, keeping the glows continuous without showing the results underneath. Each opening rebuilds the complete native view and layer tree, rather than resizing a retained presentation between the footer and header. Callbacks and selection behavior stay in the controller. Layout finishes before the opening fade, including when switching popup types.

 ## Translation
 
-Search for **Conjure Translate** and open it. Enter English in the search bar, choose a provider, then press Return or click **Translate**. Typing alone never sends text.

Choose a provider in the pill-shaped header selector, enter text in the search bar, then press Return or click **Translate**. Typing alone never sends text. When the translation is available, the action changes to **Copy**: press Return or click it to copy the full translation and close Conjure. Command-C still copies selected output. Editing the input restores **Translate**.
 
-Editing the input, switching providers, forgetting the key, or leaving Translate cancels the active request; cancelled results are not shown. After a request fails, submit again to retry.
+Press Command-P or click the provider selector to expand a searchable action-style popup from its top edge downwards, hiding the indicator until the popup closes. A checkmark marks the current provider. Use Up/Down and Return or click a provider to select it; Escape, Back, or clicking outside closes the popup. Changing providers clears the previous result without submitting a request.
+
+The footer shows the current language pair (initially **English → Japanese**). Click it or open **Actions** with Command-K to change the source language, change the target language, or swap them. Language choices are saved locally and apply to both providers. Changing languages clears the previous result without submitting another request. The input hint and output accessibility label follow the selected pair. Escape closes an open action/provider picker first and dismisses the window only when no picker is open. Back closes the picker first, then returns to the launcher and restores your search. Command-W always dismisses the entire window.
