/* KUMIM — folha de estilo da marca ("Azulejo verde").
   Cerâmica clara de fundo, rejunte nas linhas, ferro na tinta e o verde do azulejo como acento.
   O azulejo ponta-de-diamante (quadrado com losango central) é o motivo gráfico: aparece no
   símbolo do wordmark, no favicon, no fundo do herói e nos marcadores de lista.
   Mesma arquitetura dos sites da Garoa e da Kirano (chrome + landing + artigo + contato) — quem
   mantém um deles não precisa aprender outro vocabulário de classes; só os tokens e as fontes
   mudam. Tipografia: Bricolage Grotesque (títulos, wordmark, botões), IBM Plex Sans (corpo) e
   IBM Plex Mono (rótulos, números, migalhas). */
