/* PHASE 3b (Brand Kit V2) — JOIN THE LAND.
   Replaces the old "Another World" cracks concept with a bright, Pixar-tone
   "monsters live here" social hub. Each card is a window frame with a
   monster peeking in and a mocked feed inside.

   Per BRIEF V2 §6-8:
   - Row 1: Instagram + TikTok (large cards)  — ハピモン① / オイモン
   - Row 2: Official LINE (medium card)        — シーパーズ右版
   - Row 3: X / YouTube / note (small, COMING SOON)
