ShootBoard Capture Web requires the ShootBoard macOS app to be installed and open.

Review steps:
1. Install and launch the ShootBoard macOS app.
2. In ShootBoard, open Settings > Browser Capture.
3. In the Firefox section, keep the Gecko ID matching the submitted extension.
4. Click Install or Repair Firefox Connection to install the Native Messaging manifest.
5. Confirm that the Firefox connector diagnostic is ready.
6. Reload the Firefox extension if it was already open.
7. Open a public web image in Firefox.
8. Use the right-click menu action Add Image to ShootBoard.
9. Confirm that the image appears in the ShootBoard Library or selected moodboard.

Expected behavior if ShootBoard is closed: the extension displays an error asking the user to open ShootBoard.

The extension source is not minified or bundled. The XPI contains readable JavaScript, HTML, CSS, locale files, and image assets directly.
