/* ============================================================================
   The application shell.
   ----------------------------------------------------------------------------
   Recovered from commit 03a81f2^, which deleted 1327 lines from src/style.css
   as collateral damage in a commit whose subject was "Add blog: Git as Database".
   Every rule below styles an element src/main.ts mounts, so an unstyled shell
   meant the live demo opened as a default 300x150 iframe in the top left corner
   with the loading text overflowing it. That is what a visitor saw when they
   pressed the primary call to action.

   Token names are remapped onto brand/tokens.css. Nothing else was changed.
