   Splash de abertura ("vire o celular" + botão JOGAR) + Fullscreen toggle

   Combina com playersbar.css (mesmos tokens de cor/safe-area).

   Substitui a antiga pílula discreta #orientationHint por uma
   TELA DE ABERTURA fullscreen com botão JOGAR. O botão libera o
   jogo SEMPRE (não depende de detectar orientação — funciona mesmo
   com a rotação travada no celular) e aproveita o toque pra pedir
   fullscreen + tentar travar landscape.
