 * Área do aluno — estilos próprios (sem build: o servidor da Hostinger não roda Node). Spec §17.
 * Marca do site thiagoheoli.com.br: vermelho #fb004f, azul #176be0, marinho #12395f; Outfit (títulos) + Inter (texto).
 * Só modo claro. Base 390 px, WCAG 2.2 AA. Limite ~60 KB: acima disso, o player vai para aluno-pratica.css.
 *
 * Regras de cor
 *   --ta-blue   ação principal (botões). Texto/link azul usa --ta-blue-ink (passa AA também sobre o fundo).
 *   --ta-navy   âncora da marca: barra de navegação, títulos, destaques escuros.
 *   --ta-red    SINAL, nunca texto pequeno nem erro: ícones, ponto do Revisar, selo "ao vivo", botão da aula
 *               ao vivo (texto branco em negrito ≥ 18,66 px), chefão e celebração.
 *   erro        --ta-err sobre --ta-err-bg (rosado); acerto --ta-ok sobre --ta-ok-bg. Sempre cor + ícone + texto.
 *   faixas      [data-band="iniciante|basico|intermediario|avancado"] define --ta-band (sempre com o nome escrito)
 *               e --ta-band-ink (texto na cor da faixa, AA sobre o fundo e o branco).
