-- ds.page: Getting Started

-- ds.copy-regular:

Each component in the design system comes with detailed
documentation. You can access the documentation for any
component by visiting the component's page on the FifthTry
site. This includes explanations of how to use the component,
its attributes, and examples of how it works in different scenarios.

;; Some comment

Removing just the last line (Some comment) renders the page with the paragraph but nothing is rendered (white page) when that comment is present.

The above file required design-system in a package to work.

Here's the FASTN.ftd file for reference:
