June 2025: Implemented an ESLint-based governance rule to enforce direct sub-package imports for Picasso components, improving code modularity, maintainability, and potential build-time optimizations across the repo. The new rule prevents importing from the main @toptal/picasso package within sub-packages and promotes importing components directly from their specific sub-packages, aligning with Picasso's design-system goals of cleaner architecture and faster builds.
