Your CSS tells a story.
Do you know what it says?

47 shades of gray in your design tokens. Specificity wars you didn't know existed. 12 competing font stacks across your codebase. Project Wallace reveals the big picture from every angle.

The blind spot

CSS grows in every direction.
The big picture becomes invisible.

Every team reviews components. Nobody reviews all stylesheets. Over time, small inconsistencies compound into systemic problems that hide in plain sight.

  • Colors multiply quietly

    What started as a clean palette becomes 140+ unique values. Off-brand grays, duplicate blues in different formats, opacity hacks nobody remembers.

    invisible drift
  • Specificity creeps upward

    Every quick fix adds another layer. Before you know it, selectors are fighting each other and overrides are the norm instead of the exception.

    growing complexity
  • Design systems drift silently

    Tokens get duplicated. Custom properties multiply. Font stacks diverge. Nobody notices until the bundle is 300kb and the design review falls apart.
