/* ==========================================================================
   ROGUS FERRAMENTAS: folha de estilo
   Site institucional: machadinhas multifunção e Draga Articulada.
   Tema escuro e quente (marrom, laranja forja), fotos grandes, 3D em destaque.

   Regras de desenho (tiradas de sites de marcas de ferramenta: Gränsfors,
   Leatherman, Gerber, Estwing, Stihl):
   - Laranja só onde importa: botão, número, estado ativo. O resto é marrom.
   - Cantos retos (6 a 14 px) e botões em caixa alta: cara de ferramenta,
     não de aplicativo.
   - Linhas finas separam; caixas com borda só quando agrupam uma compra.
   - Números grandes e alinhados (tabular-nums): peso, medida, preço.
   - Espaço generoso e sempre o mesmo entre seções.
   Feito para carregar leve em celular e computador fraco: sem framework,
   fonte no próprio site, animações mínimas e desligáveis.
