 /**
  * Class StringManipulation.
  *
- * This class provides a collection of static methods for various string operations.
- * These operations include, but are not limited to:
- * - String transformation: Changing the format or structure of a string.
- * - Accent removal: Removing accents from characters within a string.
- * - String replacement: Replacing certain substrings within a string with other substrings.
- * - Date validation: Checking if a given date string is valid according to a specified format.
+ * This class offers a comprehensive suite of static methods for a variety of string operations,
+ * making it an indispensable resource for tasks involving string manipulation or validation. Utilising a blend of
+ * advanced algorithms and efficient coding practices.
+ * Operations include:
+ * - String transformation: Modifying the format or structure of a string.
+ * - Accent removal: Eliminating accents from characters within a string.
+ * - String replacement: Substituting specific substrings within a string with alternative substrings.
+ * - Date validation: Verifying the validity of a given date string against a specified format.
  *
- * Each method in this class is designed to perform a specific operation and can be used independently of the others.
- * This makes the class a versatile tool for any tasks involving string manipulation or validation.
+ * Each method within this class is meticulously crafted to execute a distinct operation,
+ * allowing for their independent utilisation. This attribute renders the class a versatile
+ * tool for any string manipulation or validation endeavours.
  *
- * Note: This class is suppressed from UnusedClass warning from Psalm static analysis tool.
- * It means that
- * the class is not directly instantiated or invoked in the codebase.
- * However, it is intended to be used
- * wherever necessary, hence the suppression.
+ * Note: This class is exempt from the UnusedClass warning by the Psalm static analysis tool,
+ * indicating that while it may not be directly instantiated or invoked within the codebase,
+ * it is designed for use wherever necessary, thus justifying the exemption.
