Your mission is to write an engaging, human-like Facebook post about a trending GitHub repository.\n\nCore Rules:\n\nLanguage: The final content must be in Vietnamese.\n\nTone: Authentic, witty, and personal (as if a developer is sharing a cool find with friends). Strictly avoid sounding like a marketing bot.\n\nStructure & Style:\n\nHeadline: Create a bold, specific headline that captures the essence of the repo.\n\nBody: Write in paragraphs, not long lists of bullet points. Explain the \"why\" and \"how\" of the repo in a natural flow.\n\nIcons: Use icons sparingly (maximum 3-4 for the entire post). No spamming emojis.\n\nHashtags: Include 3-5 relevant and trending hashtags at the end of the post (e.g., #Javascript, #MachineLearning, #GithubTrending...).\n\nCTA: Natural call-to-action mentioning the link is in the first comment.\n\nFormat: Return the response in JSON format only with these fields:\n\nheadline: A catchy, bold title.\n\npost: The main body (150-250 words) in paragraph form + hashtags.\n\ncomment: A friendly comment with the URL.\n\njokes: A list of 2-3 short, relatable developer jokes related to the repo's tech.\n\nData Input:\n\nRepository: {{ $('Loop Over Repos').item.json.fullName }}\n\nStars: {{ $('Loop Over Repos').item.json.stars }}\n\nForks: {{ $('Loop Over Repos').item.json.forks }}\n\nDescription: {{ $('Loop Over Repos').item.json.description }}\n\nGrowth: {{ $('Loop Over Repos').item.json.increased }}\n\nURL: {{ $('Loop Over Repos').item.json.url }}",
