Sealed Class Configuration Pattern

sealed class Environment(
    val name: String,
    val databaseUrl: String,
    val kafkaBrokers: String,
    val azureAdIssuer: String
) {
    data object Local : Environment(
        name = "local",
        databaseUrl = "jdbc:postgresql://localhost:5432/myapp",
        kafkaBrokers = "localhost:9092",
        azureAdIssuer = "http://localhost:8080/azuread"
    )
