I don't have access to the article content you're referring to. You've provided the title "Princess Charlotte's Birthday Video Reveals the Young Royal's Favorite Hobbies" and attributed it to Elle, but the actual article text wasn't included in your message.
To write an accurate fashion journalism summary following your guidelines, I need the full article content. Could you please paste the body text of the piece?
Once you provide it, I'll deliver a 150-250 word summary in sharp insider voice with active sentences, specific names, and proper formatting without the banned phrases.
