+ *                                E.g. when inside an HTML attribute or TITLE element, only plaintext is allowed,
+ *                                But when found inside a P element, rich formatting is allowed.
+ * @param array|null $attributes  Configured parameters of the Bit, if provided.
+ *                                E.g. `<//wp-bit:hello-dolly year="2024">` produces `array( 'year' => '2024' )`.
+ * @param mixed      $context     Context passed into the Bit from the surrounding system.
+ *                                This argument is not yet specified and will always be `null`.
+ *
+ * @return mixed An HTML template for rendering into the page, either as a plain string or in array form.
