only. Every route renders its own title/description/canonical/og:*/twitter:* via (react-helmet-async). Do NOT re-add a sitewide , og:* or twitter:* here — the static HTML pre-render emits BOTH the index.html head AND the Helmet output, so a sitewide description ships on every page alongside the real one and crawlers (SE Ranking, Ahrefs) report it as duplicate metadata. Helmet dedupes , so the fallback title below is safe. -->
