   台灣脆快樂指數 × 《迷航狐狸夢》 — EVENT build
   The band IS the page: one solid field of mood-colour —
   terracotta / gold / slate. The island is knocked out of it
   in cream fragments. The score is the main character: the
   brightest, most anchored element on screen; everything
   else recedes one step. Matte, no gradients.
   & Venture grounded · hooks per HOOKS.md unchanged.
