Build and debug multiple isolated design systems in a Next.js app: style-* body classes, cookie/localStorage sync, FOUC prevention, light/dark coexistence, SSR/hydration, iframe component previews, parent↔iframe theme sync, and design tokens. Use when switching themes flashes wrong styles, iframe previews ignore the picker, or docs and preview disagree.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Next.js Multi Design System Practical workflow for apps that ship **more than one Design System / visual style** in a single Next.js surface (docs, marketing, component showcase). This is **not** a basic light/dark theme toggle guide. It covers isolation of multiple style systems (`style-*`), persistence across SSR, and preview iframes that must match the parent picker. ### Scope | | | | --- | --- | | **In scope** | Multi DS switching, tokens, FOUC, cookie/SSR, iframe preview sync, docs↔preview parity | | **Out of scope** | Single-theme apps, generic CSS architecture, unrelated component APIs | --- ## When to use * One Next.js app hosts several named Design Systems (e.g. Nova, Vega, Glass). * Users switch DS without full reload and must not see the wrong tokens flash. * Component / block previews render in an **iframe** and must follow the parent. * Light/dark mode must coexist with a DS that has its own default appearance. --- ## Architecture (what usually works) ### 1) One active style class on a root element Map each Design System id → a single CSS scope class on `body` (or a dedicated root): ```text default → style-nova comfort → style-vega …

How to install
mdr add miladjoodi/skills/nextjs-multi-design-system@sha256:d71099146d700689The line at the top of this page pins the label git:20261011.ac45e0b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
