Build a fast, static website for an experimental digital zine. The look should feel raw and anti-grid—brutalist, with intentionally jarring micro-animations and oversized type. All articles live as local Markdown files. Each article can declare a theme in its front matter that changes layout, typography, color, and motion presets so pieces can look radically different. Use Astro for the site and introduce interactive islands only where interaction is truly needed (Solid preferred). Keep pages lightweight and quick on mobile by minimizing JavaScript and assets. No user accounts or backend beyond the static build. Provide a clear content structure, a theme system, and a few sample themes to demonstrate variety without sacrificing performance.
