   Renovate Cafe — design system
   A "drafting table / blueprint workshop" aesthetic: warm paper, blueprint
   ink, a carpenter-pencil amber accent, and Space Grotesk numerals built for
   a calculator. Light is the default; [data-theme="dark"] is a blueprint night.
   Self-hosted variable fonts. Vanilla CSS, no framework.
