/* 1. TOKENS
   As variáveis --sereno-user-* são injetadas pelo Customizer via
   wp_add_inline_style() e servem apenas como *entrada*: cada token real
   usa var(--sereno-user-x, padrão). É isso que mantém o modo escuro
   funcionando mesmo com cores personalizadas — o inline style define
   outra variável, nunca o token final. */
