Zero-build privacy policies with Astro

I am still confused what exactly this tool is doing. I clicked on "examples" in the hope of finding an example of a generated policy. But it only gives examples of the configuration, not the output.

I wonder how often do privacy policies change, for the average site, to merit investing in a dedicated library that renders them dynamically. Assuming that the default solution is a static page.

"Zero-build privacy policies": "Everything runs at build time", what?
