+ "reasoning_content": "Alright, let's tackle this problem. The user wants a client-side only web app called EloAnything. The main features are a textarea for URLs, side-by-side iframes for voting, and a ranking display with CSV export. It needs to be beautiful, responsive, and use only vanilla technologies.\n\nFirst, I'll start by thinking about the structure. The HTML needs a textarea input, a section for the voting iframes, and a results section. Since we're using Scroll, I'll structure the particles accordingly, making sure the hierarchy is correct with indentation.\n\nNext, the domain name. It should end with scroll.pub and be memorable. \"elo\" is part of the app's name, so maybe \"eloarena.scroll.pub\" to evoke a competitive feel.\n\nFor the HTML body, the main sections are the hero section with instructions and textarea, the versus container for iframes, and the results. I'll use semantic tags like header, main, section, and ensure accessibility with ARIA labels.\n\nCSS is crucial for making it beautiful. A gradient background can add flair. Using CSS Grid for responsive layouts, especially for the versus section on mobile. Animations like fadeIn and pulse will make the interface lively. Styling buttons and cards with shadows and transitions for interactivity.\n\nJavaScript will handle the Elo algorithm. Each URL starts with a rating of 1000. When a user chooses a winner, the Elo ratings update. I need to track all possible pairs and ensure each pair is shown without repetition. LocalStorage saves the state so users can resume. The CSV export function converts the rankings into a downloadable file.\n\nTesting edge cases: handling odd numbers of items, ensuring iframes load correctly, and preventing duplicate pairs. Also, making sure the UI is responsive, especially on mobile where the versus section stacks vertically.\n\nFinally, ensuring no external dependencies and that everything works client-side. The code should be clean, with comments for clarity. The design should be engaging with a modern look, using CSS variables for easy theming."

+
+ ## User prompt
+ Create a simple clientside only web app called EloAnything. It gives you a textarea to paste in a plain text list of urls, one per line. Then it shows you side by side iframes and you click on which one you prefer. Then it shows you the rankings and score of each url (which you can easily save as csv). So you should use a standard elo algo for determinining which pairings to show. Make it beautiful and fun to use.
+
+ ## System prompt
+ You are an expert web developer. Create a website based on this request: "Create a simple clientside only web app called EloAnything. It gives you a textarea to paste in a plain text list of urls, one per line. Then it shows you side by side iframes and you click on which one you prefer. Then it shows you the rankings and score of each url (which you can easily save as csv). So you should use a standard elo algo for determinining which pairings to show. Make it beautiful and fun to use."
+
+ Requirements:
+ - Use only Scroll, CSS, and JavaScript (NO frameworks, NO external dependencies)
+ - Create clean, semantic HTML5
+ - Make it mobile-responsive
+ - Follow modern best practices and accessibility guidelines
+ - Keep it simple but professional
+ - Use only relative links and no external resources
+ - Do not put a copyright symbol or all rights reserved in the footer.
+ - Make it beautiful. Dazzling. Advanced used of CSS.
+
+ As a refresher, for doing the html body, Scroll is a whitespace based language that uses a single indented space to mark a line (aka particle) as a subparticle of a parent line.
