/* Aqualita Pulse — tema claro compartilhado (ADR-IMPL-019/020).
   Fonte única de verdade dos tokens de cor e componentes comuns usados por
   Pulse Coach, Pulse Manager e Portal do Aluno (Pulse Live tem sua própria
   folha — é um telão passivo com ambientação diferente, gradiente animado
   de fundo; estas 3 telas são de trabalho/leitura, priorizam legibilidade
   de tabelas/formulários em vez de flourish visual). Cada página mantém só
   o CSS realmente específico do próprio layout.
