/* ==========================================================================
   Design system — Calculadora Automotiva
   Extraído do protótipo "transições fluidas" (paleta, tipografia, glass,
   status-pill, gradiente ciano→roxo→rosa, abas com indicador deslizante).

   Carregado DEPOIS de style.css de propósito: os tokens antigos
   (--bg-card, --border, --accent, --text-muted…) são reescritos aqui em
   função da paleta nova, então as telas de módulo que já existem
   (CAS3, FRM, DME, FA, FSC, NCD, CBB, SFA Token, KDS) passam a usar o
   visual novo sem precisar de nenhuma alteração nos seus templates.
   Só o que o protótipo trouxe de novo — abas, orbs, pills, data-row,
   animação escalonada — mora aqui como componente global.
