+# Frontend Rules
+
+- One component per file, named with PascalCase
+- Use Server Components by default in Next.js — add `'use client'` only when needed
+- Tailwind utility classes for styling — avoid inline styles
+- All interactive elements must be keyboard accessible
+- Include `aria-label` on icon-only buttons
+- Use semantic HTML (`<nav>`, `<main>`, `<section>`) over generic `<div>`
+- Images require `alt` text
