Seniority isn't a measure of how much you know. It's a measure of how well you know what you don't know — and how systematically you close those gaps before they become incidents.

Design Systems Are Grammar, Not Paint

A design system isn't a component library. It's the grammar of a visual language — and like any grammar, it only becomes interesting once people start bending the rules.

Token-as-Grammar

A finite set of choices that constrains composition the way grammar constrains a sentence. The strong version of this pattern asks you to remove tokens, not add them.
