Public slug example: preserve the Unicode edge case

A public Slug Generator example should show a harmless input title, expected slug, and actual slug. If the problem involves accents, Turkish dotted and dotless I, emoji, or punctuation, keep those characters in the synthetic title. Do not expose a private draft URL or account identifier. State the locale or normalization rule expected. This makes it possible to diagnose whether the problem is transliteration, case conversion, separator handling, or a route collision.
