   app.css — hand-written stand-in for the Tailwind utilities the app uses.

   In the Claude artifact, Tailwind's core utilities were provided for us.
   Outside it they are not, so this file defines exactly the 97 classes the
   app actually references, using Tailwind's own default values, plus the
   small "preflight" reset Tailwind normally applies to bare HTML elements.

   If you add a new Tailwind class to app.jsx, add it here too or it will
   silently do nothing.
