NanoBananaPro: UI/UXウェブモックアップ

Design a clean, modern homepage for a tech-focused blog website. Use a minimalist layout with a full-width hero section at the top, including the brand logo in the top-left, a navigation bar with "Home, Categories, About, Contact," and a central headline with a subheadline. Use sans-serif typography (Inter / Satoshi). Include three featured article cards with thumbnails, titles, category tags, and short summaries. Add a prominent CTA button labeled "Read Latest Insights" below the hero text. Footer should contain social icons, newsletter signup field, and minimal copyright text. Maintain generous white space and soft shadows for a premium editorial feel.
