// prerender-route-heads.mjs — INTERIM SEO-collapse fix. The app is a client SPA; crawlers read
// the static index.html shell, so every route shipped the homepage <title>+canonical=/+desc.
// This postbuild step writes dist/<route>/index.html per static route with a UNIQUE per-route
// <title>, self-referencing <link canonical>, AND per-route <meta description> — the last read
// straight from each page's own useSEO() call (single source of truth, no divergence; only the
// simple ${brand.business.name}/{BUSINESS_NAME} substitutions are resolved). CF Pages serves
// these file-based, before the /* → /index.html SPA fallback. Replace with vite-react-ssg later.
