Build an ultra-fast, reading-first blog that feels effortless to browse. Use Astro with Tailwind for styling, and keep client-side JavaScript to a bare minimum (progressive enhancement only). The look should reflect Swiss modernism: a precise typographic scale, a consistent grid, and generous negative space. Authors write posts in Markdown; every article page is statically generated; an RSS feed is produced automatically; and the home page allows simple tag-based filtering without a heavy framework. No backend—just a clean, accessible, static site that loads lightning-fast and prioritizes readability.
