/* beforethem.css — sub-site BeforeTHEM dentro do csurface.io.
 *
 * O site da CSURFACE é claro, com o navy só no hero. O BeforeTHEM é outro
 * produto e ganha identidade própria: preto no lugar do navy, o ciano do logo
 * oficial (#4FEDD2, "Before" em ciano e "Them" em branco) e elementos de
 * interface de máquina (HUD, varredura, telemetria). Tudo fica escopado em body.bt-site, ligado pelo base.html quando
 * o slug começa com "beforethem", para não vazar para o resto do site.
 *
 * O preto não é #000: os vídeos dos robôs têm fundo ~#05080c, e um preto puro
 * deixaria a borda do vídeo visível. #04060a casa com eles.
