// Case conversion & truncation
"hello world".ToSlug()                              // "hello-world"
"hello world".ToCamelCase()                         // "helloWorld"
"hello world".ToPascalCase()                        // "HelloWorld"
"hello world".ToSnakeCase()                         // "hello_world"
"hello world".ToTitleCase(new CultureInfo("en-US")) // "Hello World"
"Hello World".Truncate(6)                           // "Hello..."
"ab".Repeat(3)                                      // "ababab"
"hello".Reverse()                                   // "olleh"

// Normalization
"  ciao    mondo  ".NormalizeSpaces()      // "ciao mondo"
"café".RemoveDiacritics()                  // "cafe"
"Hello! @#$%".RemoveSpecialChars()         // "Hello"
"<p>Hello <b>World</b></p>".StripHtml()    // "Hello World"

// Privacy / PII masking
"mario@mail.it".MaskEmail()   // "m****@mail.it"
"3331234567".MaskPhone()      // "333*****67"

// Search & comparison
"Hello World".ContainsAny("World", "Foo")  // true
"Hello".EqualsIgnoreCase("hello")          // true

// Validation
"mario@mail.it".IsEmail()     // true
"12345".IsNumeric()           // true
"Hello".HasMinLength(3)       // true

// Encoding / decoding
"Hello".ToBase64()            // "SGVsbG8="
"hello world".UrlEncode()     // "hello+world"
