Ruby on Rails is a full-stack, convention-over-configuration web framework that popularized the MVC pattern for the modern web, still widely used by startups and established products (GitHub, Shopify, Basecamp) that value its productivity-focused conventions. Rails doesn't set a distinctive `X-Powered-By` header by default, so AIWebsiteDetector instead looks for Turbo/Hotwire markup (`data-turbo-*` attributes, `rails-ujs`, `@hotwired/turbo`) that Rails' default JavaScript stack injects into rendered pages, plus the `X-Runtime` response header Rails' middleware adds to every response.
