+ "reasoning_content": "Okay, I need to create a website for experimenting with dot products using only HTML, CSS, and JavaScript. Let me start by understanding the requirements. The user wants it to be interactive, mobile-responsive, and visually appealing with advanced CSS. No frameworks or external dependencies, so everything has to be vanilla.\n\nFirst, the domain name. It should end with scroll.pub and be memorable. Since it's about dot products, maybe something like \"dotprod.scroll.pub\" or \"vectordot.scroll.pub\". \"dotlab.scroll.pub\" sounds catchy and short. Yeah, dotlab.scroll.pub works.\n\nNext, the structure. The main page should have two vectors input, visualize them, and show the dot product result. I'll need sliders for each vector component, a visualization canvas, and real-time updates. Also, some educational content explaining the formula and steps.\n\nFor the HTML structure using Scroll syntax, I'll start with a header, main content, and footer. The main section will have input controls, the canvas, and the explanation. Using semantic tags like section, article for better accessibility.\n\nCSS needs to be modern and responsive. Using CSS variables for colors, grid layout for the controls and visualization. Flexbox for responsive design. Animations for the result display to make it pop. Media queries for mobile adjustments, stacking elements vertically on smaller screens.\n\nJavaScript will handle the interactivity. Event listeners on the sliders and number inputs to update the vectors. A function to calculate the dot product whenever inputs change. The canvas will draw the vectors with arrows, using different colors for each vector. Also, updating the formula display with the current components and result.\n\nAccessibility considerations: labels for all inputs, aria-live regions for dynamic content, proper contrast ratios. Using rem units and relative sizing for responsiveness.\n\nTesting the slider and input synchronization. Making sure the canvas redraws smoothly. Handling the vector visualization with arrowheads, maybe using trigonometry to calculate the arrow points.\n\nFor the CSS, a gradient background for a modern look, subtle shadows on cards, and hover effects on interactive elements. The color scheme should be professional but vibrant, using blues and oranges for the vectors to stand out against a light background.\n\nIn the footer, just a simple credit without any copyright symbols. The overall design should be clean, with plenty of whitespace and clear typography.\n\nPutting it all together: the Scroll syntax for HTML, making sure the indentation is correct. The CSS styles in the style.css file, and the JavaScript handling the logic. Testing on different devices to ensure responsiveness."

+
+ ## User prompt
+ Build a cool interact tool for experimenting with dot products
+
+ ## System prompt
+ You are an expert web developer. Create a website based on this request: "Build a cool interact tool for experimenting with dot products"
+
+ 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.
+
+ For example:
+
