/* TodoWay - app do participante.
 *
 * Linguagem: minimalismo utilitario, monocromatico quente. A cor e escassa e
 * so carrega significado: vermelho = SOS/acao sem volta, verde = conectado,
 * ambar = reconectando, azul = aviso informativo. Todo o resto e preto, branco
 * e cinzas quentes.
 *
 * Usado quase sempre no celular, no meio de um evento: alvos de toque grandes,
 * menu na base da tela (alcance do polegar) e o SOS como o botao mais forte.
 *
 * Fontes do sistema de proposito (SF no iPhone, Segoe no Windows): nao custam
 * download e a CSP (font-src 'self') nao precisa liberar terceiros. Os titulos
 * usam a serifa do sistema (Iowan/Palatino/Georgia) para o tom editorial.
