3 design systems from real websites set in Roboto: their palettes, type scales, spacing and components, measured from the live pages. Install any of them as a skill so Claude Code, Cursor or Codex builds in that style.
In Livery's library, dell.com, youtube.com and systemsethiopia.com use Roboto for their headings. Each kit records the full type scale: sizes, weights, line heights and letter spacing at every level.
Is Roboto free to use?
Each kit says whether its fonts are free to reuse, need a licence (with a free alternative named) or are style-only. Open a kit to see Roboto's licence and how to install it in your project.
How do I make my app look like one of these?
Open a kit and install it in your coding agent (one paste in Claude Code; unzip for Cursor, Codex or Windsurf). The agent audits your project, asks which areas to change and applies the design one area at a time, so you can review and revert each step.
