   VIANNA'S — assets/css/viannas.css
   ----------------------------------------------------------------------------
   CSS custom da landing page (Bootstrap 5.3.3: apenas reboot+grid+utilities em
   vendor; TODOS os componentes — botões, navbar, collapse, form — são escritos
   aqui à mão, mantendo as convenções de classes Bootstrap para futura conversão
   em theme e107.

   Conceito visual: "sistema modular 2×2" (logótipo = grelha 2×2 de blocos).
   Estilo: blueprint arquitectónico + serviço caloroso. Linhas finas, cantos
   quase retos (0–6px), espaçamento generoso. Sem sombras iguais.

   Paleta exacta (extraída do logótipo):
     navy  #102450 · slate #3B507D · taupe #BAB6A6 · creme #E8E3CE · mist #F0EFEB
     Branco puro permitido; preto apenas em opacidades baixas (sombras).

   Tipografia: 'League Spartan' (display) + 'Sora' (corpo).
   >>> e107: quando auto-alojar fontes, pode substituir 'Sora' por
       Glacial Indifference (gratuita, OFL — fora do Google Fonts).
