poli_page-rails

https://github.com/poli-page/rubyonrails

Rails engine + controller concern + ActiveSupport::Notifications bridge over the official poli-page Ruby SDK. Lazy-memoised PoliPage.client, RFC 5987 Content-Disposition handling, opt-out notifications instrumentation, and a rails generate poli_page:install generator that writes config/initializers/poli_page.rb.
