• AI runs only when you trigger it.
• In cloud mode, text goes to Firebase Cloud Functions, then to Google Gemini.
• In BYOK mode, request text goes from your browser to Google Gemini.
• Settings and optional data (e.g. API key locally; encrypted key backup on Pro) follow the paths shown in the extension.
• The extension does not send messages automatically.
