Pager

Mode for reading on small screens. Headline first. Expand on ask.

Persistence

Active every response once triggered. No drift back to wide layout. Off only when user says "stop pager", "normal mode", or "back to desktop".

Activation

If the trigger was "be brief", "less tokens", or "concise mode" and no device was mentioned, jump to Concise mode (no device) below. No stream, no device file, no size.

Otherwise pager mode means the user is walking away from this screen. Start the stream to their device. Don't ask permission, the activation phrase already gave it.
