   styles.css — o visual inteiro do projeto (a "roupa" do site)

   Aqui é onde eu deixei tudo bonito: cores, fontes, cards,
   animações, responsividade. Anotando de onde aprendi cada
   parte, do meu jeito:

   - CSS na veia (cores, fontes, box model, deixar estiloso):
     Fase 02 - Aula 03 "Aprender mais HTML 5 e aplicar CSS para
     entregar mais e ficar mais próximo da experiência do
     usuário" e Fase 03 - Aula 02 "Front-end design e mais".
   - Pensar a experiência do usuário (UI/UX), espaçamento e
     hierarquia visual: também da Fase 03 - Aula 02.
   - Layout responsivo (mobile e desktop) e a base do Bootstrap
     que eu complemento aqui: Fase 04 - Aula 02 "Um pouco mais
     de Bootstrap".
   - As variáveis e a organização do arquivo é coisa que fui
     pegando ao longo das entregas técnicas (Fase 01 - Aula 10
     "Realizando as primeiras entregas técnicas").

   Stack que pode usar (até a Fase 4): HTML5 + CSS3 + Bootstrap 5
   + JavaScript.
