Cambia — make your UI adapt to each user

@epode/cambia is a command-line tool that lets your app's interface personalize itself for every user — automatically, and privately on their device. It builds on DESIGN.md, the simple Markdown file that describes your design system.

npx @epode/cambia init      # add adaptive settings to your DESIGN.md
npx @epode/cambia check     # make sure they're valid
npx @epode/cambia tailwind --out theme.js   # turn your design tokens into a Tailwind theme
npx @epode/cambia skill     # set up your AI coding assistant (Claude / Cursor)

What it does

You label, once, what each component is (a table, a primary button, a form field…) and which parts are allowed to change per person (like row density or default sort) versus what should always stay the same. From then on, the companion runtime quietly tailors those parts to each user as they use your app — no dashboards, no setup for the user, and nothing sent to a server.

• Adapts to each user — the interface fits how each person actually works.
• Private by default — preferences live on the device; nothing is tracked or transmitted.
• One small file — it all lives in the DESIGN.md you already have.
• Works with your AI tools — drop in a rule so Claude or Cursor build to your design system.
