TEST deployment check, please ignore

Build tEST deployment check, please ignore.

Context: This is a test post made by the site operator to verify a production deployment. It is not a real idea and will be removed by the admin.

Requirements:
- Ship the smallest version that delivers the core value above, nothing more.
- Pick a stack you can deploy in a day, and state the choice before writing code.
- Handle the empty state, the error state and the offline case explicitly.


Start by listing the screens, then build them one at a time.
