/* ARU PDF - folha unica. Layout "iceberg" (proposta ARUPDF-Iceberg, aplicada em 2026-11-05).
   A pagina e um oceano: a superficie e um azul-ardosia claro, a linha d'agua corta o heroi e o fundo escurece conforme se
   desce (gradiente do body). Cobre e ambar da paleta Sovereign Soul sao os unicos acentos quentes. Modo unico, escuro.
   As variaveis com prefixo color/font/space/transition sao o contrato visual dos modulos de ferramenta: nao renomear. */
