Heroku fonts and type scale

How do I build a site that looks like Heroku with AI?
Open the Prompt tab above, change its first line to what you are building, and paste it into Lovable, v0, Bolt, Claude Code or Cursor. For a whole project, install the Claude skill or the Cursor rule instead, so every screen keeps the style. Build something original: keep Heroku's look, not its name, logo or copy.
