Control surfaces

Good engineering shows up in the felt details: local data, keyboard flow, server boundaries, and small interactions.

The problem

Some products are not defined by one clever feature. They are defined by how carefully every small control behaves.

The build

Write explores local-first authorship. One revisits a to-do list as a craft exercise. Keep tests how server components and personal data can mix cleanly.

Learning

The details are the product.
