//! Open three tabs at distinct URLs, iterate the [`Browser::tabs`] registry,
//! and print every tab's URL — the canonical P4 multi-tab smoke test.
//!
//! Demonstrates:
//!   - [`Browser::new_tab_at`] (open + navigate in one step).
//!   - [`Browser::tabs`] (snapshot of every live tab the registrar tracks,
//!     including the auto-attached `main_tab`).
//!   - [`Browser::tab_count`] (cheap len read on the same registry).
//!
//! Each opened tab is its own session — closing the [`Browser`] tears them
//! all down via the shared Connection drop path.
