/* =============================================================================
 * telos-boot-mascote.css — a SEGUNDA tela de carregamento do site: a do
 * bichinho. A primeira é a abertura da Home (telos-intro.js).
 *
 * O site tem duas telas de carregamento e só duas. Esta aqui é uma só, dividida
 * hoje em duas famílias de classe por causa de onde nasceram (o banco de
 * questões e a área do aluno); o desenho é o mesmo arquivo, então os dois lados
 * mudam juntos.
 *
 * Antes era ouro chapado (#d4a857) com um círculo, uma barrinha e um bichinho
 * parado. Passou a falar a mesma língua da abertura: fundo escuro com vidro,
 * halo prateado que abre, anel, a linha (seam) atravessando a tela, o bichinho
 * entrando com peso e as frases subindo por trás de uma máscara.
 *
 * Não pede nenhuma mudança de markup: o halo, o anel e a linha vêm de
 * pseudo-elementos. Piso de fonte 16px. prefers-reduced-motion desliga tudo.
