O resolveShareLinkOgImageUrl absolutizava /api/media/file/… contra o siteUrl do global metadata (hoje https://jorgesolla.com.br, servido pelo WordPress antigo), que responde 404 no proxy de mídia — o WhatsApp lia título/descrição mas derrubava a miniatura (caso real do cartão plenaria-cultura, da plenária de 19/09). - resolveDeploymentOrigin (novo em seo.ts): NEXT_PUBLIC_SITE_URL primeiro (inlinado no build de produção, mesmo carrier do isStagingSite), fallback no URL do global; canonical/og:url seguem a cadeia global-first documentada — só a URL do asset muda. - Unit do resolver (env vence/fallback/vazio); int pina o env sobre um URL de global estrangeiro.
