   ParaRH - design system base (Fase 1)

   Sem Tailwind e sem build: a Hostinger nao roda Node e a CSP nao permite
   CDN. Isso e CSS escrito a mao, com tokens, para ser estendido nas fases
   seguintes.

   Direcao visual: SaaS B2B sobrio. Verde-petroleo como cor de marca, fundo
   levemente esverdeado (nao branco de consultorio, §42), numeros em fonte
   tabular porque este produto e, no fim, um painel de indicadores.
