/* =========================================================================
   Caderninho de Buteco — tema "papel pautado + comanda de fiado".
   Claro: folha de caderno (papel creme, pauta azul, margem vermelha, escrita
   à mão). Escuro: quadro de giz de boteco (lousa, giz branco e colorido).
   Sem dependências externas: fontes de escrita são as nativas do iOS/sistema,
   e a textura é um SVG inline (offline-first).
