/*
 * Domine a IA — sales page composition (CTS-108, rebuild v3).
 *
 * Camada única e limpa por cima de tokens.css (espelho intocado do DS V4).
 * Versões anteriores em ./legacy/ e no histórico git.
 *
 * Direção v3 (mesmo sistema do C01 Segundo Cérebro, alinhado ao
 * academialendaria.ai atual):
 * - header em pílula flutuante; botões pill com seta; kickers em chip;
 * - tipografia: Inter Tight pesada + Instrument Serif itálica nas ênfases;
 * - CIANO é a cor do produto (CTA, preço, acentos). Dourado zerado;
 * - herói-instrumento (o pedido ganhando camadas), diff antes/depois,
 *   oferta como empilhamento com destaque máximo;
 * - CTAs de compra com pulso lento de cor.
 *
 * Esta é a versão ESCURA (index.html). A clara é index-light.html — mesmo
 * HTML com data-color-scheme="light", sem toggle.
