§ 02 — How I work
A studio of one.
One person designs it. One person writes it. One person answers the email. The work is small on purpose — built to be finished, shipped, and quietly improved for years.

Your data stays on your device. Local-first, always.

Ship the menu-bar version. No dashboards.

Updates are quiet. Releases are rare. Software is forever.
