Static-site-generation (SSG) prerendering and SEO for the house React/Vite stack — Puppeteer prerenders public routes to static HTML at build time, generates sitemap.xml, and an SEOHead component manages meta tags, Open Graph and JSON-LD structured data. Use this when adding SEO or prerendering to a Vite SPA, when marketing/landing pages need to be crawlable, when asked about sitemaps, meta tags, structured data, or "why doesn't Google see my React page".
