- app/[[...slug]]/page.tsx replaces app/page.tsx; activeSlug from URL params
- SidebarNav and MobileNav removed from main layout (sections accordion is the nav)
- next.config.ts: output:export controlled by STATIC_EXPORT env var instead of NODE_ENV
- package.json: yarn build is standard Next.js build; yarn export is STATIC_EXPORT=true
- Mock API route: force-static + generateStaticParams for output:export compatibility
