   <h1>About</h1>
   <p>
-    Marfa grew out of a frustration. After trying more apps than I can count, every switch meant leaving something
-    behind. It also draws on experience with customer data platforms, where one well-modelled source of data is the
-    whole point.

   </p>
   <p>
-    That matters more now that agents can build an app in an afternoon. Apps can come and go; the data underneath
-    should last, and make sense to whatever reads it next.

   </p>
   <p>
-    Marfa has been rebuilt more than once this year. It began as a hosted service that tried to be compatible with
-    everything, which pulled it away from what mattered most: a sound data model and a server you can rely on. So it
-    became something you run yourself, with a Rust core under its command-line tool and native apps. Marfa Cloud will
-    follow as an optional relay for reaching it from anywhere, without holding your data.
-  </p>
-  <p>
-    It’s a personal project, not a business. It ships when it works, not before. Marfa is free and open source, so anyone
-    can run it, build on it or take it somewhere new.
