   ASSINATURA REV — camada compartilhada do ecossistema (RevClub · RevBrain ·
   RevScribe · RevLearn · RevMind).

   Espelho de `revclub/app/(club)/club-signature.css`. Traz a linguagem que a
   página de entrada do RevClub estabeleceu: grain de filme, eyebrow com
   ponto-assinatura, monograma, spotlight de card, shine de botão, índice
   editorial. Consome os tokens que o RevScribe já tem em tokens.css /
   design-system.css — sem vocabulário novo.

   ⚠ CACHE-BUST: este produto não tem build step; o navegador serve o CSS
   antigo se o `?v=AAAAMMDD` do <link> não for bumpado no MESMO commit.
