// Addendum 2 — TOTP auto-copy toast (T-M11–T-M13), proposed feature.
//
// Today, when Peach auto-copies a TOTP code it shows the generic "2FA code
// copied" toast (showToast in index.ts). The addendum asks for a dedicated
// showTotpCopyToast(secondsUntilClear) that renders a passkey-family toast
// ("2FA code copied / clears in 30s") and auto-dismisses after 3s, resetting its
// timer if a second copy lands while it is visible.
//
// showTotpCopyToast does not exist yet. This file imports the REAL inject.ts and
// activates the spec the moment the export appears — so it is an executable
// contract, not a stub that always passes. See INTEGRATION-CONTRACT.md.

import "./_setup"; // installs the chrome mock inject.ts touches at import time
