/* Badges customizáveis — EAD Cursos
 * Aplicados sobre .course-card-badge / .course-preview-badge já posicionados
 * (position: absolute) pelo tema. NÃO sobrescrever `position` aqui — `absolute`
 * já é "positioned", então ::after { inset: 0 } continua válido. Antes
 * definíamos `position: relative` aqui, o que resetava o absolute e fazia a
 * badge "sumir" da posição correta (ficava no fluxo natural).
 * Novos efeitos são aditivos: basta criar .ead-badge-effect-<nome> abaixo.
