   ARTHUR BOTELHO ARQUITETURA & INTERIORES - STYLE GUIDE & CSS
   ==============================================================================
   GUIA DE MANUTENÇÃO ESTÉTICA E DESIGN (LEIA ANTES DE EDITAR)
   ==============================================================================
   Este arquivo define toda a identidade visual, tipografia, grid estrutural e 
   animações interativas do site de Arthur Botelho.

   1. DADOS DE DESIGN EDITÁVEIS (:root - Linhas ~45 a ~70):
      - CORES DA MARCA:
        --navy: Define a cor True Blue oficial do escritório (#1E2E47). É a cor
                predominante em fundos, cabeçalho escuro e botões principais.
        --gold: Cor bronze/dourada dos detalhes arquitetônicos (#8D6E63). Usada
                para destaques, tags de seção, botões ativos e linhas de título.
        --beige / --beige-dark: Tons off-white neutros editoriais, usados para
                backgrounds suaves das seções, simulando papel de portfólio.
      - TIPOGRAFIA (FONTES PREMIUM DO GOOGLE FONTS):
        --font-title: 'Playfair Display' - Serifada elegante para títulos e H1/H2.
        --font-body: 'DM Sans' - Sans-serif contemporânea de alta legibilidade para
                     parágrafos, menus e fichas técnicas de projetos.
        Caso precise trocar as fontes, faça o link do novo Google Fonts no 'index.html'
        e atualize os valores destas variáveis aqui no CSS.

   2. AJUSTES DA CURSOR EXCLUSIVO (LIQUID GOLD CURSOR - Linhas ~135 a ~175):
      - O cursor dinâmico é controlado pelo CSS (.custom-cursor) e suavizado 
        pelo JavaScript (Lógica LERP).
      - Para alterar o tamanho normal do cursor, edite 'width' e 'height' na classe
        '.custom-cursor'. Para o tamanho ao passar o mouse em links/botões, edite 
        'width' e 'height' na classe '.custom-cursor.active'.
      - O cursor é ocultado automaticamente em telas menores que 1024px para não
        prejudicar a navegação em celulares e tablets.

   3. AJUSTES DE ANIMAÇÕES DE TRANSISÇÃO (Linhas ~24 a ~28):
      - --transition-smooth: Usa uma curva cúbica bezier premium (cubic-bezier(0.25, 0.46, 0.45, 0.94))
        para garantir deslizamentos suaves ao invés de transições lineares duras.

   4. PLACEHOLDERS E SUBSTITUIÇÕES FUTURAS:
      - IMAGEM DE PERFIL DO ARQUITETO (Seção Sobre):
        Atualmente, é exibida uma moldura sofisticada com um ícone SVG e o texto
        "Arthur Botelho - CAU A319847-2". Quando o arquiteto disponibilizar sua foto
        de perfil profissional real:
        a) Adicione a foto (com fundo neutro ou transparente) na pasta '/assets/brand/perfil.webp'.
        b) Edite a seção '#sobre' no 'index.html' substituindo a div '.profile-placeholder'
           por uma tag de imagem correspondente: 
           <img src="assets/brand/perfil.webp" alt="Arthur Botelho" class="profile-img">
        c) No CSS, estilize '.profile-img' com 'border-radius: 2px', 'object-fit: cover', 
           e 'aspect-ratio: 4/5' para se alinhar perfeitamente à moldura Jacquard.
