Servo-replacement runtime for Tauri: wires html-cat, css-cat, dom-cat, layout-cat, paint-cat, net-cat, boa-cat, ecma-runtime-cat, and web-api-cat into a single rendering + scripting pipeline. v3.3.0 honours `Max-Age` by rewriting it as an absolute `Expires` at merge time (so the v3.2 expiry filter catches it without needing a separate receipt-time field). Per RFC 6265 `Max-Age` wins over any pre-existing `Expires`; `Max-Age=0` or negative values expire the cookie immediately. The Servo no-AI policy disqualifies upstream contribution; this is the AI-built parallel.
