/* ============================================================
   GWG INTRANET — DESIGN TOKENS (Atlas Corporativo)
   PJ031 — F1 — Etapa 1
   Data: 2026-06-20

   PROPOSITO:
   Camada de tokens semanticos que ANTECEDE o design system v2.
   Por enquanto, apenas DEFINIMOS as variaveis CSS. Nenhuma classe
   utilitaria nova e criada nesta fase (isso e F2/F5).

   CARREGAMENTO:
   Inserido em base_v2.html ANTES de gwg-design-system-v2.css.
   Como o v2 nao usa :root com mesmas variaveis, nao ha conflito.

   DECISAO:
   Manter valores alinhados ao design system atual (azul-marinho
   + dourado) para intranet NAO MUDAR visualmente. Quando o Wilson
   aprovar a paleta "Atlas Corporativo" final, basta trocar os HEX.
