"""Public contact BFF helpers for Pages apps (Nuxt, React, HTML).

Inbox, public-config, and magic-link consume stay installed. The unauthenticated
``POST /api/contact`` submit route is compatibility-only: emit it when an existing
project already has that route, not for new canonical Forms projects.
