How a page is built

Scrape — each route's server HTML is stored in scraped/html/<page>.html (real markup plus nsave's serialized router payload).
Split — <header>, <main> and <footer> are cut into components/exact/<page>-{header,main,footer}.html, which each route imports through raw-loader (html.d.ts declares the *.html module).
Answers — nsave renders FAQ answers only on interaction, so scripts/inject-faq.mjs bakes the real answer text (from nsave's own payload and JS chunks, kept in components/exact/faq.json) into the markup using nsave's own collapse pattern: grid-rows-[0fr] -> grid-rows-[1fr]. Re-run it with npm run inject-faq (idempotent, renumbers panel ids per file).
Render — components/ExactPage.tsx injects the markup and boots the behaviours.
