Prototype launch / interactive example

A sample workout
that stays saved.

A list is a starting point. Save a sample, retry the same request, then reload to see what a complete journey needs to handle.

Browser-only synthetic demo. Use invented details, never real health or personal data. Samples stay in this browser’s local storage; nothing is sent to us.

Try it. Reload it. Check it.

These invented entries last until you leave or reload this page.

    Beyond the
    happy path.

    A valid entry survives reload. Invalid input is rejected. Retrying the same request keeps one record. A storage failure is reported without claiming a save succeeded.

    This example uses localStorage, not a backend. There are no accounts, cloud sync, cross-device persistence, multi-tab coordination, medical features, backups or app-store release. Clearing browser data removes the samples. A separate local kit tests HTTP and SQLite; that backend is not running here.
