"""Regression guard for issue #1355 — the Cookbook *download* error toast used
the default ~1.2s duration, so an actionable message like "tmux is required …"
vanished before it could be read. The serve path already used multi-second
durations; the download-failure toasts now match.

cookbookDownload.js pulls in browser globals so it can't run under node; this
guards the durations at the source level.
