/* DPMG Design System — Shell da área pública sem menu (US-1131, ex
 * dpmg-components.css)
 * =====================================================================
 * Renomeado na Fase 4 (US-1131) para refletir o escopo real: hoje este
 * arquivo é linkado SÓ por script/template/base_script.html (bloco
 * css_area), o wrapper fino que templates/html/base.html usa para a área
 * pública "sem menu" (ia/, script/, gerador_docx/gerador_docx_script.html,
 * planilha/planilha_sem_menu.html — confirmado via grep: nenhum outro
 * template linka este arquivo, nem a área restrita nem os hubs com menu
 * de templates/html/base.html). Não é compartilhado entre "as duas áreas"
 * do site — não redistribuído porque, verificado, ele NÃO é reaproveitado
 * fora dessa família de páginas; ver PRD US-1131 para a análise completa.
 * Continua carregado depois de dpmg-tokens.css.
