Pup - the AI's own browser

// pup birth page script (2.0.632). Lives in its own file because an extension page's default content
// security policy refuses inline scripts: an inline version left every title at plain "PUPBIRTH", so pup's
// token lookup timed out on every open and the window showed for the 3 s it waited (measured, 2.0.631).
// 2.0.726: fills in who opened the window, why and where it is going, and counts the wait (John, 2026-10-19).
