   DESIGN.md - UI design systems format shared with AI

   Google's Stitch has introduced DESIGN.md, an open-source file format designed to standardize how UI design systems are shared with AI tools. It combines machine-readable design tokens (colors, typography, spacing) with human-readable context explaining design intent, enabling AI to generate consistent, brand-aligned interfaces without repeated manual explanation. The format includes validation tools like accessibility checks and integrates with workflows such as Tailwind and CI pipelines, aiming to become a universal design contract that reduces friction and improves designer-developer collaboration.

   Tailwind CSS 4.2 Ships Webpack Plugin, New Palettes and Logical Property Utilities

   Tailwind CSS 4.2.0 ships a first-class webpack plugin that eliminates the need for manual PostCSS configuration, bringing webpack projects to parity with Vite integration. The release adds four new muted color palettes (mauve, olive, mist, taupe), expands logical property utilities for internationalized and RTL layouts, and delivers a 3.8x recompilation speed improvement across all integrations. Teams still on v3 can use the automated migration tool, though some rough edges remain around @apply usage in component libraries.
