/* =====================================================================
   Painel interno da NUX Tech — identidade REAL da marca, corrigida em
   2026-07-28 (ver docs/design-tokens-nuxtech.md). A versão anterior
   deste arquivo usava violeta/preto/Bebas Neue — extraído por engano
   das variáveis CSS de nuxtech.com.br, que por sua vez NÃO bate com a
   marca real. A marca real (evidência: logo oficial em
   /var/www/nuxtech/admin/icon.svg, theme-color de produção, e
   tailwind.config.js do admin-panel) é azul marinho + âmbar + Inter —
   a mesma paleta do painel administrativo antigo (admin.nuxtech.com.br),
   que afinal sempre foi a identidade correta, não uma paleta "legada"
   descartável como eu tinha documentado antes.
