UI Pattern Library

Interface patterns lifted out of projects I actually shipped. Each one renders live in an isolated frame and comes with its markup, its styles, its behaviour, and the prompt that rebuilds it from scratch.

cc-dash

A dashboard and Model Context Protocol server for a project portfolio whose entire state lives in markdown files.

No database: the files are the source of truth, and git is the audit log.
