Treat easter eggs as a system, not scattered tricks

Hidden interactions need structure

Easter eggs are easy to add badly. One-off hidden commands and isolated puzzle fragments feel clever during implementation, but they become difficult to maintain once the site grows.

The better approach is to define each egg as a small product unit with:

• a unique id
• a clear trigger
• an explicit reward
• a persistence rule

Why the registry matters

A registry keeps the hidden layer from bleeding into normal navigation. It also makes it possible to reason about coverage and duplication before the site becomes messy.

That is the difference between:

• a playful secondary layer that rewards exploration
• a fragile set of surprises that breaks every other release

Implementation rule

The hidden layer should never block a normal visitor from reading, navigating or contacting the site owner.

That rule is stricter than it sounds, but it is the only way to keep the experience coherent.
