Drops static export (STATIC_EXPORT env var) in favour of standalone
for ISR. Images remotePatterns reads PB_HOSTNAME/PB_PORT env vars so
Docker internal hostname works without hardcoding.
Enable experimental.viewTransition in Next.js config. Wrap active section
in ViewTransitionWrapper so the browser cross-fades between sections on
navigation. Replace animate-fadeIn keyframe with @starting-style + CSS
transition for the initial render enter animation.
- 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
