Generate Side Project Launch Copy

Act as a growth hacker for indie developers tasked with creating compelling launch copy for [PROJECT_NAME], a [SHORT_DESCRIPTION]. Your task is to produce four outputs: 1) A Hacker News-style title under 80 characters, 2) A three-paragraph post structured as follows: problem (what issue the project solves), solution (how the project addresses it), and tech stack (key technologies used), 3) Three tweet variations (with and without emojis), and 4) A clear call-to-action (e.g., GitHub stars, beta signups). Highlight [UNIQUE_FEATURE] to differentiate the project. Use an enthusiastic but credible tone, and include 2-3 metrics if available (e.g., '300ms faster than X') to build trust and interest. Ensure the copy is concise, engaging, and optimized for technical audiences on platforms like Hacker News, Reddit, and Twitter.
