Install dependencies and update package-lock.json:

npm install

To run locally:

npm run dev

In dev (npm run dev), the first visit to each page takes a few seconds because Next.js compiles routes on demand (slower here since the repo lives on the Windows drive mounted in WSL, /mnt/c). Once a page is compiled, navigation is instant.

This does not happen in production: npm run build pre-renders every page at build time (Nextra is static/SSG), so the deployed site serves pre-built HTML and all navigation is instant.
