## Description

CSSVarVault is a Firefox extension built for design-system and frontend teams that rely heavily on CSS custom properties. It audits how variables are declared and consumed on a live page, then surfaces where variable references exist without matching declarations. The goal is to make CSS token drift visible early, especially on large sites with layered stylesheets and partial theme rollouts.
