Users should not have to relearn how to browse, select, play, or return. Navigation, controls, and focus should follow conventions other apps have been using for years, and the same action must keep the same meaning from one screen to the next. New features must extend what the app does, not redesign user habits.

Meaningful choices about appearance, behavior, and available features must belong to the server owner. Once configured, the experience cannot be changed, expanded, or reinterpreted by an update. Any new feature that alters what users see or how the app behaves must remain disabled until the owner enables it.

Every screen and interaction has to hold up after the first impression wears off. Focus must be obvious, navigation can't do anything unexpected, and getting somewhere should never take more clicks than it reasonably needs. A feature isn't finished until it feels deliberate, predictable, and easy to use.
