Using playwright-rs

Rust bindings for Microsoft Playwright. This crate is a thin JSON-RPC client to the upstream Playwright server, so the API mirrors playwright-python / java / .NET semantics. When unsure about a method's behavior, the upstream Playwright docs are the authoritative reference.

Drift discipline. The canonical API tour lives in the crate-level rustdoc at https://docs.rs/playwright-rs — that's compile-checked against the actual code. This skill is the "what to reach for, what to avoid" overlay: durable conventions, not a method-by-method reference. Two build gates hold it to the crate: the Rust code block below is compiled against the real API, and every cargo feature and browser engine the crate exposes must be named somewhere in this file, so a capability cannot ship here undocumented.
