   Catálogo de Bad Smells de Comunicação — Spell (DCC/UFLA)
   Micro-site autocontido: não usa css/style.css do site do laboratório.
   Os design tokens replicam a identidade oficial do Spell (paleta extraída
   do logo) para que o catálogo pareça parte da mesma família visual, mas o
   cabeçalho, a navegação e o rodapé são próprios.
   HTML5 + CSS3 puro. Mobile-first. WCAG 2.1 AA.
