/* ─── Transição entre apps (Portal / AdsPulse / Backlog) ───────────────────
   Overlay full-screen verde escuro com 3 bolinhas pulando.
   - Aparece quando voce clica num link pra outro app (fade IN, ~250ms)
   - Mantem visivel durante o reload completo do browser
   - O app destino renderiza o mesmo overlay INLINE no HTML (no flash branco)
   - Quando o app destino monta + dados prontos, fade OUT (~400ms)
