// Keyless browser coverage for pending queue actions through the shipped Web
// composition and real HTTP/SSE wire. A replay override parks the active turn
// so two ordinary follow-ups remain addressable while the page edits one and
// removes one. The queue uses an existing recorded model
// call; this scenario owns only the user-visible mid-turn golden.
