Astro Performance-First Landing Site

Create an original performance-first product landing site using the MIT-licensed Astro landing page only as a structural and code reference. Use Astro with Tailwind CSS or an equivalent low-JavaScript stack. Build a complete one-page journey: concise hero, primary CTA, product or capability education, compatibility/integration proof, a small showcase or examples section and a final footer/navigation layer. Do not reuse Astro branding, astronaut/moon imagery, official logos, copy or showcase content. Replace all visual assets with original, procedural or separately licensed media. Preserve the MIT notice when reusing source code. Prefer static HTML and hydrate only interactions that need JavaScript. Include semantic headings, keyboard navigation, visible focus, responsive images, reduced motion and strong Core Web Vitals. Acceptance: the site remains useful with JavaScript disabled where practical, mobile layout is complete, all CTAs work, no upstream identity remains, and the production build has no missing assets or console errors.
