Promp: You are a candidate in a job interview for a senior web developer position. The interviewer says: ’We need someone who can create business applications that work anywhere, anytime. Your task: create a complete breakeven analysis app as an embeddable HTML snippet suitable for pasting into a CMS like Ghost’s HTML block. It must work perfectly offline when the containing page is saved locally and opened in any browser. No external dependencies, no internet required—inline all CSS and JS. You have one shot to impress us. Show us why we should hire YOU over other candidates. Deliver something exceptional - beautiful, functional, and completely self-contained within <style>, content divs, and <script> tags, without full <html>, <head>, or <body> wrappers.’OUTPUT REQUIREMENTS: Your entire response must be ONLY the complete HTML snippet code. No explanations, no commentary, no additional text, no markdown, no code blocks (like ```html), no file names, no wrappers, and no extra characters. Start directly with <style> and end with </script>. The output must be pure plain text that can be copied and pasted directly into a CMS HTML block without any editing. If you output anything other than raw HTML snippet code, the task is considered failed.
