DiscoverTiles.kt held only one non-composable top-level decl (`enum class AvatarShape`), so detekt wanted the file renamed. The enum had two variants discriminating circle vs. rounded; a Boolean `circular` arg is the same information with no extra cost — collapses the `when` into a one-line `if`. Two call sites updated.
