/* ---------- Fallback com metricas casadas (anti-CLS) ----------
   A folha do Google Fonts carrega sem bloquear a renderizacao (media="print"
   + onload), o que e otimo pro FCP mas garante que o texto apareca primeiro
   na fonte do sistema e SO DEPOIS troque pra Montserrat/Inter. Nessa troca as
   letras mudam de largura e altura, o conteudo se reacomoda e a pagina
   "pula" — no relatorio isso aparecia como CLS 0,243, atribuido ao glow do
   hero (que e ancorado pelo bottom e por isso se move junto; ele era o
   sintoma, nao a causa).

   Estes @font-face nao baixam nada: sao a Arial local reescalada com
   size-adjust/ascent-override pra ocupar o MESMO espaco da fonte final.
   Assim a troca acontece sem deslocar nada. */

/* ---------- Marca IS7 ----------
   O simbolo entra como mascara e a cor vem de var(--grad) — o mesmo degrade dos
   botoes e dos titulos. Antes era um <img> com filter:brightness(0) invert(1),
   que apagava o degrade e deixava a marca branca chapada no tema escuro.
   Pintando por --grad ela acompanha o tema sozinha e mantem contraste nos dois.
   O arquivo e o glifo ja recortado (sem os 75% de espaco vazio do original).

   Caminho ABSOLUTO de proposito. Com "assets/..." relativo, o endereco muda
   conforme quem carrega o CSS: no site principal o build embute a folha no
   HTML da raiz e resolve certo, mas as paginas de proposta carregam
   site_v2/site.css como arquivo externo — ali o relativo virava
