style: align translation text and reduce explanation size

 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.
 
+The launcher, emoji picker, and Translate share `ActionPill` for footer styling, alignment, spacing, and keyboard indicators: primary action with Return first, then Actions with separate Command and K keycaps. Controllers supply the buttons and retain their targets, enabled state, and popup behavior.
+
+The header’s trailing edge is constrained to the footer’s trailing edge. The translation provider pill and footer pill therefore share the same 8-point right inset and 36-point height.

 ### Global shortcuts and launch at login
 
 In Settings, choose a **Global shortcut destination**: **Applications**, **Conjure Emoji**, **Conjure Notes**, or **Conjure Translate**. Choose **Record Shortcut…** and press a combination containing Command, Option, or Control. For example, select **Conjure Emoji** and record Command-Shift-Space to open the emoji picker directly. **Clear** disables only the selected destination's shortcut. No shortcuts are assigned by default; existing launcher bindings are preserved.

 ## Translation
 
-Search for **Conjure Translate**, identified by its centered 🌏 icon, and open it. 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**.
+Search for **Conjure Translate**, identified by its centered 🌏 icon, and open it. With empty or whitespace-only source text, Return or **Swap languages** reverses the source and target without submitting a request. **MyMemory** translates the text in one step: press Return or click **Translate** to submit. Typing alone never sends text.
 
-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.
+With **OpenAI · gpt-6-luna**, enter the text first, then press Return or **Add context**. The original text stays visible while the search bar becomes a second input for the situation: where you encountered it, who said it to whom, or the intended tone. Press Return or **Translate** to send both inputs. Context is optional; Return with blank context translates without it, rather than swapping languages. OpenAI returns the translation first, followed by a one- or two-sentence explanation in the target language. Context helps resolve meaning, tone, and register; if the text conflicts with the situation, the explanation flags the mismatch instead of silently changing the meaning. Nothing is sent when advancing to the context step.
 
-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.
+The translation uses 20-point primary text; OpenAI's explanation below the blank line uses 14-point dimmed secondary text. The original-text preview, translation, and explanation share a left edge.
+
+When the translation is available, the action changes to **Copy**: press Return or click it to copy the full output (including OpenAI's explanation) and close Conjure. Command-C still copies selected output. Editing the current input clears the result; editing context keeps the original text. The action is disabled while translating.
+
+The footer places the current primary action and its Return keycap before **Actions**, whose Command and K keys use separate keycaps, matching the launcher.
+
+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. Switching away from OpenAI during the context step restores the original source text; context is not sent to MyMemory.

Command-W always dismisses the entire window.
 
 Editing the input, changing languages or providers, saving or forgetting the key in Settings, or leaving Translate cancels the active request; cancelled results are not shown. After a request fails, submit again to retry.
 
 - **MyMemory:** No account or key required. Limits are 500 UTF-8 bytes per request and [5,000 characters per day](https://mymemory.translated.net/doc/usagelimits.php) for anonymous use.
 - **OpenAI:** Requires an API key, access to `gpt-6-luna`, and sufficient API billing. Manage the key in **Settings > Conjure Translate**: **Save Key** stores it in macOS Keychain; **Forget Key** removes it. Translate never saves a key implicitly. Requests disable API response storage, but OpenAI's retention policies still apply.
 
-**Translation sends your input to the selected third-party provider. Avoid sensitive content.** There is no automatic fallback between providers. MyMemory never receives your OpenAI key.
