# Astro v6 Architecture Rules (Strict Mode) ## 1. Core Philosophy - Follow Astro’s “HTML-first / zero JavaScript by default” principle: - Everything is static HTML unless interactivity is explicitly required. - JavaScript is a cost → only add when it creates real user value. - Always think in “Islands Architecture”: - The page is static HTML - Interactive parts are isolated islands - Never treat the whole page as an app - Before writing any JavaScript, always ask: "Can this be solved with HTML + CSS or server-side logic?" --- ## 2. Component Model - Use `.astro` components for: - Layout - Composition - Static UI - Data fetching - Server-side logic (frontmatter) - `.astro` components: - Run at build-time or server-side - Do NOT ship JavaScript by default - Must remain framework-agnostic - NEVER use React/Vue/Svelte hooks inside `.astro` --- ## 3. Islands (Interactive Components) - Only u…
