It looks like they want to replace the current app with a dark IDE layout. I should update the contents of index.html, style.css, and app.js, while making sure to keep the utils.js import intact. I’ll replace the app.js script, but first, I need to remove the stray import in the CSS block and ensure everything is aligned with the provided code.\n**Crafting file replacements**\n\nI'm planning to update index.html to a minimal format that simply loads style.css and app.js. For app.js, I’ll use the JS from the prompt while correcting that stray \"import\" line at the end of the CSS. The comment indicates that I need to ensure it exists, so I'll place the import at the beginning of app.js. Plus, I have to check that the utils.js path is correct. I’ll create three SEARCH/REPLACE blocks for the files, then summarize the changes concisely.\n\nI will replace the current HTML, CSS and JS with the new dark IDE layout and the corresponding app script (integrating the existing fitCanvasToDevice import and fixing JS placement).\n\nindex.html\n```index.html\n```\n\nstyle.css\n```style.css\n```\n\napp.js\n```app.js\n```\n\nSummary: I replaced index.html, style.css and app.js with the dark IDE layout and a cleaned app script that imports fitCanvasToDevice, builds the UI, procedural brushes and layer/canvas management, and fixes JS placement so the app runs with the new UI.","page_description","The page introduces \"Kreska Pro Studio\" with a clean, simple HTML structure.
