//! Smoke test for the synchronous API (`SyncPage`/`SyncElement`).
//!
//! Runs in a plain `fn main` (no tokio) against a local server, to verify the
//! `block_on` wrappers — including ones that await + sleep internally like
//! `wait_data_packet` — don't deadlock and the newly-added methods work.
//!
//! Run with: `cargo run --example sync_smoke`
