/* =====================================================================
   TRAKYA — Institutional Site Stylesheet
   =====================================================================
   Estrutura deste arquivo (nesta ordem):
     1. Reset leve e variáveis de marca (cores, tipografia, espaçamento)
     2. Utilitários globais (container, botões, links, foco de teclado)
     3. Acessibilidade (skip-link, sr-only, prefers-reduced-motion)
     4. Header / navegação
     5. Seções da página, na ordem em que aparecem no HTML (metodologia AIDA)
     6. Rodapé
     7. Media queries de responsividade (mobile-first: base = mobile)

   Boas práticas aplicadas:
     - Variáveis CSS para a identidade visual oficial da Trakya
       (fonte: material de identidade visual, paleta HEX #115560 / #CDEA80 / #F4F4F4)
     - Mobile-first: estilos base pensados para telas pequenas,
       com breakpoints progressivos (600px, 900px, 1200px)
     - Contraste de texto verificado para WCAG 2.1 AA (mín. 4.5:1 em texto normal)
     - Estados de foco visíveis em todo elemento interativo (acessibilidade de teclado)
     - Sem uso de !important em regras de layout; especificidade controlada por convenção de nomes
