I need a clean, modern-and-minimalist frontend that lets visitors choose how they feel and instantly see music suggestions on the same page. The scope is strictly UI/UX, so everything will live in HTML, CSS, and a dash of vanilla JavaScript—no backend calls, databases, or APIs. Key interactions • Mood selection buttons centred on the screen, styled consistently with the overall minimalist palette. • A responsive layout that rearranges gracefully from mobile portrait to large desktop without breaking alignment or typography. I’ve sketched the flow and have reference assets ready; your job is to translate that into polished, production-quality code, comment it clearly, and hand over a single zipped folder containing the HTML file, CSS stylesheet, and any lightweight JS. Acceptance criteria 1. Loads flawlessly in the latest Chrome, Firefox, Safari, and Edge. 2. Lighthouse mobile performance score ≥ 90. 3. No external frameworks—plain HTML5/CSS3/JS only. If you enjoy crafting sleek, responsive pages and can deliver pixel-perfect fidelity, this should be a smooth sprint.
