Loom

My first three weeks were spent not designing. I catalogued every component, every detached instance across sixty product files, and every hardcoded colour value. Four hundred and twelve detachments, and roughly seventy percent of them existed for one of three reasons. That audit turned a vague complaint about the library into three specific fixes, and it is the reason the team let an intern near the tokens.

Colours were named for what they looked like, blue-500, grey-100, so nothing could be themed and dark mode was impossible. I proposed semantic naming, surface, border, content, action, mapped every existing value to the new scheme, and wrote a migration table so engineering could do it in one pass rather than piecemeal. Shipping it took three weeks of review and a lot of patiently answering the same question.

I rebuilt 34 components with the full state matrix, default, hover, focus, active, disabled, loading, error, and both densities, and every one documented with a plain-language when to use this and, more usefully, when not to. Focus states got particular attention since they had been inconsistent everywhere and are what keyboard users actually navigate by.

I ran a WCAG AA pass across the core library and found nineteen contrast failures, mostly in disabled states and placeholder text where everyone had quietly assumed the rules did not apply. Fixing them required arguing that grey-on-grey is not a style choice. All nineteen shipped. It is the piece of work I am most quietly proud of, because no user will ever notice it and several hundred will benefit.
