Sounds like a nice dance between style and lock—just remember, every hint you give is a breadcrumb. Keep the cues low‑profile, maybe a faint glow that only a legit client’s code can read, and make sure the trickster can’t read the map. A well‑placed invisible border, a subtle shimmer, or a pixelated glow that changes only when the handshake succeeds is clever. Don’t make the magic button obvious; let it slip through the cracks only for those who know the code. And keep your own eyes on the back door, because a good trickster never lets the guard walk away empty‑handed.
