+ * The CEP is not 8 digits.

+ * Usually thrown **without** a request ever being made — the client checks the
+ * format before going to the network. It is also thrown when the API answers
+ * 400 to a CEP that passed local validation, in which case it carries the
+ * API's own message.
+ *
+ * Extends `\InvalidArgumentException`: this is an argument error.
