   style.css — Estilos da loja DB Imports (index.html)
   -------------------------------------------------------------
   MOBILE-FIRST: os estilos base são pensados para telas pequenas
   (<576px). Breakpoints usam min-width para telas maiores:

     base                     -> mobile (<576px)
     @media (min-width: 576px)  mobile grande (celulares landscape)
     @media (min-width: 768px)  tablet
     @media (min-width: 992px)  desktop
     @media (min-width: 1200px) desktop grande
     @media (min-width: 1600px) ultrawide

   Técnicas aplicadas:
   - clamp(min, pref, max) p/ tipografia e espaçamentos fluidos
   - Grid/Flexbox p/ layouts que se reorganizam automaticamente
   - Containers com max-width + margin auto + padding lateral fluido
   - Imagens fluidas (img/video: max-width: 100%; height: auto)
   - box-sizing: border-box global (sem estouro por padding/border)

   Organização por seções (use Ctrl+F para navegar):
     1. Variáveis de tema (:root)          -> cores, gradientes
     2. Reset e regras base (body, inputs)
     3. Top Notice Bar                     -> faixa de avisos no topo
     4. Navbar Glassmorphism               -> header (logo + carrinho)
     5. Menu mobile + barra de filtros     -> hambúrguer, chips, busca
     6. Hero / Banner Topo                 -> apresentação + busca
     7. Trust Badges Grid                  -> selos de confiança
     8. Main Layout Grid + Sidebar         -> filtros (busca/categoria/marca)
     9. Categorias de Produtos             -> cards que abrem o info modal
    10. Área dos Produtos (cards)          -> grade gerada pelo JS
    11. Product Detail Modal               -> modal "Ver detalhes"
    12. Info (info-section/list)           -> reutilizados nos itens do FAQ
    13. Toast & Animações de "adicionado"
    14. Modern Cart Drawer & Overlay       -> gaveta do carrinho
    15. Checkout Screen / Modal            -> formulário de pedido
    16. Modal de Confirmação               -> limpar carrinho
    17. Botões Flutuantes                  -> carrinho + voltar ao topo
    18. FAQ Section                        -> accordion de perguntas
    19. Footer                             -> rodapé
