Make every served byte crawlable without executing JS, remove off-brand
copy, and cut third-party requests.
- Copy: replace off-brand terms (survival/crisis/collapse) in title, meta,
OG/Twitter, JSON-LD and webmanifest with on-brand preparedness copy.
Update App.vue i18n page_title/meta_description (EN+DE) too, since the app
overwrites the head at runtime. Reconcile area count to the real 6.
- Prerender: vite-plugin-seo-snapshot injects a static <noscript> snapshot
(real <h1>, content, <a href>) after #app. JS users ignore <noscript>, so
the live app/UX is unchanged; curl/no-JS crawlers get real content.
- 404: nginx now returns true 404s on unknown paths (no soft-200 SPA
fallback) with a branded 404 page.
- Sitemap: drop no-op hreflang alternates, add <lastmod>.
- Fonts: self-host Space Mono / DM Serif Display / Barlow (woff2, latin +
latin-ext, font-display: swap); preload above-the-fold faces. No more
fonts.googleapis/gstatic requests.
