Main: px-4 py-6 on mobile (was px-8 py-12). Section accordion:
mb/py on inactive links tightened to 1/1 on mobile, space-y-0
between sections. Active title text-xl on mobile to prevent
wrapping at ~400px, matches inactive title size.
- 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
