Adds Tailwind CSS v4.2 browser runtime patterns for HyperFrames compositions. Use this when you scaffold with `hyperframes init --tailwind` and need utility classes, CSS-first theme tokens, or help migrating from v3 syntax. It covers the pinned `@tailwindcss/browser@4.2.4` runtime, the `window.__tailwindReady` contract, and how to keep styles deterministic for video rendering. The guidance is narrow: it's for composition HTML, not the studio package which still runs v3. Useful if you're getting missing styles on frame 0 or building class names dynamically and need to understand what the browser runtime can actually see before capture starts.
